從兩岸科技一百強, 看台灣怎麼辦?

面臨中國　Taiwan，你該怎麼辦？
《數位時代》撰文＝童儀展

從這篇文章中, 可以幫助思考在兩岸競合趨勢的轉變中, 企業未來策略的選擇
有些經典觀察, 深怕遺漏, 特別摘錄如下:

「因為中國以廣大內需為巨額籌碼，並藉由外商與台商的力量，不斷建立起屬於自己對產業的影響力，然後積極發揮基礎研究、軟體優勢，培養出後續一代又一代的本土科技公司，」拓墣產業研究所所長陳清文

新中國概念股所代表的將是，「日後要能被中國業者所善用，並從中獲得中國本地市場，或是隨著中國企業拓展全球腳步而獲取最大利益的台灣企業，」中華經濟研究院所長陳信宏

「勝出或淘汰須跟上中國市場解構腳步然而未來台灣科技業的成長動能，將逐漸來自於市場力量的驅動，而不再是技術力量。這一點，從中國與印度等具備規模經濟的新興市場崛起就可得到驗證，」主筆童儀展

「未來，台灣企業成長模式勢必由過去的技術鏈轉為供應鏈，」拓墣產業研究所大陸研究中心主任張瑞華

Multicast and Broadcast Services in Mobile WiMAX

Multicast and Broadcast Service (MBS) is defined as an interoperability feature (IO-MBS) by WiMAX Forum and will be tested in Wave 2. MAC and Physical layer related to MBS already defined in IEEE802.16e. Hence, the implementation between MS and BS is more clear. Currently, WiMAX forum not yet define the interface between MBS server and ASN GW but some common industry implementation methodology can be done by vendor.

ASN GW can be a proxy for multicast and broadcast just like an multicast router in IP world. When the MS need to receive multicast service, an IGMP join message for a specific multicast channel will be sent to ASN GW. After some authorization procedure, ASN GW will notify BS to setup multicast channel with the requesting MS through DSA messages which is defined in 802.16. After DSA procedure, MS can receive the multicast channel information from MBS_MAP. Before MS terminate the multicast reception, an IGMP leave message will be sent to AGW. Broadcast service can also be acquired through DSA process and MBS_MAP but bypass the IGMP process.

Mobility function of MBS service can be supported through MBS zone. When the MS moving in the BS culster within the same MBS zone, there is no need to setup new connection ID.

Channel Coding and Modulation Required by WiMAX Forum and IEEE 802.16e

Although the Convolution Turbo Code (CTC) is optional in 802.16e, yet both of the Convolution Code(CC) and Convolution Turbo Code(CTC)are required to be implemented in BS and MS according to WiMAX forum's Mobile WiMAX System Profile Release 1 and will be tested in Wave 1. 64-QAM in uplink direction is optional in 802.16e and WiMAX forum's System Profile.

Mandatory Modulation and Coding Rate in Fixed WiMAX OFDM mode

The coding scheme of Reed-Solomon (RS) error correction code can be denoted as (n, k, T), where
n is the number of overall bytes after encoding,
k is the number of data bytes before encoding,
T is the number of data bytes which can be corrected. From the property of RS code, T=(n – k )/2.

The encoding is performed first passing the data in block format through the RS encoder and then passing it through the convolutional code (CC) encoder. Hence,
Coded block size = (the number of overall bytes after RS encoding) / CC code rate

IEEE 802.16-2004 OFDM mode require that the RS-CC overall encoding rate 1/2 should be used as the coding mode when requesting access the network (except in subchannelization modes, which use only convolution code 1/2 and bypass RS code)and in FCH burst.

For example in 16-QAM modulation using RS code (64, 48, 4), the number of overall bytes after RS encoding is 64. And then using CC code rate 2/3, the resulting coded block size is 64*(2/3) ie.96 which is also resulting the overall coding rate 1/2 (ie. 48/96).

Scalable OFDMA selected by WiMax Forum

在802.16-2005 section 8.4.2.3中規定Channel Bandwidth與sampling factor之間的關係, 由Channel Bandwidth(BW), number of used sub-carrier(Nused)與sampling factor可決定sub-carrier spacing, 在相同的sampling factor之下, sub-carrier spacing是固定的
WiMAX forum 為了提高設備實作時的互連性, 特別依據802.16-2004及802.16-2005再明確規範出各項必要及選項功能, 完整描述於WiMAX_Forum_Mobile_System_Profile Release 1.0的文件中,
OFDMA with TDD是System Profile Release 1的基本要求, 台灣選用2.5GHz屬於WiMAX forum定義的2.496GHz~2.69GHz Band Class 3, 移動台MS必須支援整個Band Class的frequency range, 基站台BS則可依BS Vendor宣告支援特定Band Class的部分frequecy range, 但至少需支援到最大channel bandwidth的3倍

Channel Bandwidth為1.25MHz, 5MHz, 10MHz, 20MHz時, 皆為1.25Hz的倍數, 查表得sampling factor n=28/25
Channel Bandwidth為1.75MHz, 7MHz, 8.75MHz時, 皆為1.75MHz的倍數, 查表得sampling factor n=8/7

在802.16-2004 Section 8.4.2.4提到sampling frequency Fs=floor(n*BW/8000)*8000
BW為5MHz的sampling frequency Fs=floor((28/25)*5/8000)*8000=5.6MHz
BW為10MHz的sampling frequency Fs=floor((28/25)*10/8000)*8000=11.2MHz

又sub-carrier frequency spacing可由此推算 deltaF=Fs/Nfft
所以在保持sub-carrier frequency spacing不變的條件下, 只要變動FFT size即可支援不同的channel bandwidth具OFDMA功能, 也就是scalable OFDMA
BW為5MHz若使用Nfft=512, 則BW為10MHz時, Nfft=1024, 而sub-carrier frequency spacing皆維持為deltaF=5.6/512=10.94kHz

Useful symbol time Tb= 1/deltaF, 所以BW為5MHz及10MHz的useful symbol time Tb=1/10.94=91.4usec

在Mobile WiMAX System Profile release 1的section 4.1.1.4中選定cyclic prefix(CP)的必要項目為1/8, 以保護傳送中因multipath fading造成的影響, 所以Guard Time Tg=Tb/8=91.4/8=11.4usec, 加上cyclic prefix 以後的OFDMA symbol duration Ts=Tb+Tg=91.4+11.4=102.9usec, 以Mobile WiMAX System Profile release 1的section 4.1.1.5規定frame length的必要項目為5ms, 因此一個frame可以有5/0.129=48個OFDMA symbol
The guard time can protect the multipath delay spread whose delay time is smaller than guard time. The common pratice about the delay spread in home is 50nsec and the delay spread in outdoors is 300nsec. The guard time in WiMAX is much larger than those common pratice delay spread values.

公式摘要:
Nused= number of used sub-carrier
Nfft= smallest power of 2 greater than Nused
Sampling Frequency Fs=floor(n*BW/8000)*8000
Sub-carrier frequency spacing deltaF=Fs/Nfft
Useful symbol time Tb=1/deltaF
Guard Time Tg=Tb*CP
OFDMA symbol duration Ts=Tb+Tg

使用OFDMA時, 當channel bandwidth變大時只要改變FFT size, 仍可維持相同的Sub-carrier frequency spacing及OFDMA symbol time
In other words, the basic principles of Scalable OFDMA are outlined as:

[1]Sub-carrier spacing is independent of channel bandwidth
[2]The number of sub-carrier scales with channel bandwidth
[3]The smallest unit of bandwidth allocation, based on the concept of subchannels, is fixed and indepedent of bandwidth and other modes of operation.
[4]The number of subchannels scales with bandwidth and the capacity of each individual subchannel remains constant.

Downlink and Uplink path of WiMax BS for OFDMA part

Scalable OFDMA的設計主要由OFDM核心以及傳送與接收Subchannelization等兩個部分所構成。
OFDM核心控管FFT
OFDM核心控管FFT運算與Cyclic Prefix的附加與移除，FFT的大小是一個參數，必須在設計時進行指定。
‧下行傳送
下行OFDM核心模組執行Frequency Domain輸入資料的IFFT，並增加Cyclic Prefix到產生的Time Domain資料之上。Cyclic Prefix附加模組包含一個控制器，可以做為從FFT輸出封包的緩衝區，並增加相對於輸出封包開端一樣的內容到輸出封包的結尾之上，如此一來將需要非常大的記憶體資源，如果數據機在TDD模式下運作時，其中的嵌入式記憶體可以跟上行OFDM核心共享。

‧上行接收
上行OFDM核心模組執行Time Domain輸入資料的FFT作業，並移除Cyclic Prefix，必須提供同步化訊號以指定Cyclic Prefix的起點，移除Cyclic Prefix模塊會在Cyclic Prefix期間忽略資料，並將剩餘的Sampling 寫入到FFT輸入緩衝區中。
當Channel特性變更之後，在Cyclic Prefix時間的起點之後，便可能不會一直有同步脈衝，這個硬體必須被設計來處理這種狀況，但是脈衝的變化程度將被限制在Cyclic Prefix的時間之內，且起始脈衝將不會在Preamble Symbol完全被Phase Lock前出現。

Subchannelization及產生Pilot
Frequency Domain所代表的資料是由控制模組所構成，用以產生相對應的RAM儲存模組的讀取與寫入位址。未處理的輸入時槽將放在記憶體模組中，並透過跨越Frequency Domain的方式來分配資料樣本，用次通道化模組來構成OFDMA符號，並產生必須的引導與保護載波。
FFT的大小必須在合成時進行設置，但是在運作模式(FUSC/PUSC)與IDCell的值可以在執行時進行設置，在PUSC模式下，至少需要有兩個資料符號傳送到緩衝區，在這個模式中，兩個符號將必須同時被構成。
Desubchannelization取得資料Slot
解次通道化模組將執行以下的處理程序，以便從接收到的OFDMA符號中萃取出資料時槽：
．重新整理所接收的副載波，並從FFT巨集核心功能中組成OFDMA符號。
．萃取出Null Subcarrier與Pilot Subcarrier。
．輸出每個資料Slot。

FFT and IFFT in OFDMA

Wimax實體層定義了幾種不同的型式, 其中一種為OFDMA, 當資料以OFDMA Symbol來表示時, 這些Symbol信號可以在時域上及頻域上拆解成一些簡單信號(subcarriers in frequency domain)的組成, 在此就用到了傅利葉轉換, 在IEEE 802.16e中定義了四種不同大小的FFT Size: 128, 512, 1024, 2048
一般信號可以從兩種觀點來看, 一者是從Frequency Domain來看, 信號有如頻譜分析儀上所見, 橫軸為頻率, 縱軸反應該信號在此頻點上的振幅, 另一者是從Time Domain來看, 信號如示波器上所見, 橫軸為時間, 縱軸反應該信號在此時間點的振幅, 透過Fourier Transform可以將信號在這兩個Domain間做轉換

為了討論信號在系統中不同的響應, 所以通常會把信號拆解成幾個簡單信號的組成, 如此, 當我們了解系統對這些簡單信號的響應時, 也就進而可以得知組合信號的響應了

傅利葉級數告訴我們, 在特定條件下, 周期為T的周期性信號可以用一系列的Sin及Cos函數所表示

但是實務上並非所有信號皆為周期性, 不過我們可以想像將在T時間內非周期性的信號轉換為周期為T的周期性信號, 如此則所有信號皆可虛擬轉換為周期性信號
利用下列三角函數等式

再定義

一般信號的傅利葉級數複數表示式可為

將傅利葉級數一般化後即為傅利葉轉換
Fourier Transform定義為(將Time Domain轉為Frequency Domain)

Inverse Fourier Transform定義為(將Frequency Domain轉換為Time Domain)

FFT則是採用較快速(Divide-and-Conquer)的方法得到計算結果
If the input (time domain) signal, of N points, is x(n) then the frequency response X(k) can be calculated by using the

第一次拆解時可以將偶數時間抽樣點與奇數時間抽樣點值分開處理, 如此使得需處理的Sample數降為2個N/2

當N=8時, 最後拆解結果則如下

Comparison of Empirical Propagation Path Loss Models for Fixed Wireless Access Systems

VTC05_Empirical-ComparisonOfPathLossModel
網路規劃中談論三大主要課題: Coverage Forecast, Capacity Forecast, Frequency Planning, 在Coverage Forecast方面在top-level design之前, 會先以Propagation Path Loss Model來概算涵蓋區域內需要多少發射台, 過去有許多以實務經驗為依據的Propagation Path Loss Model被提出, 如ECC-33 model, Stanford University Interim(SUI) models, COST-231 Hata model, 但是否可應用於WiMax FWA系統, 仍有待驗證
在英國由University of Cambridge, BT Mobility Research及其他民間公司於2003年在Cambridge地區的Rural, Suburban, Urban三種不同環境下實際量測3.5GHz的FWA系統的path loss, 進而驗證上述三種Model在FWA的預測之可用性.
結果顯示, 一般來說SUI及COST-231 Hata model在三種環境下針對path loss都會產生過度預測的現象, 也就是會產生較高的建置成本預估. 採用ECC-33 model計算時則比較接近實測值, 特別是在都會區時表現更好
在Cambridge地區進行的的實驗網路有5個基站, 65個CPE, 每個基站有4個AP每個AP提供90度扇區涵蓋, 這5個基站的涵蓋區包含了Rural, Suburban, Urban三種地形
在每個CPE量測點以GPS定位, 都必須在不同的接收天線高度下進行接收信號量測, 一般從10公尺到5公尺, 約隔1公尺量測一次, 信號採用3.5MHz之Channel Bandwidth, Symbol Rate設為2.5MHz, 接收天線的beamwidth為23度, 測量點主要集中在離基站250公尺至2公里之間, 約隔250公尺取一量測點, 共有300個以上的量測地點, 550個量測點, 在每個量測點每隔0.3秒紀錄一次信號強度, 至少收集100個強度值後再取平均後, 可用以計算path loss, 所得的實際值即可與三個經驗Model做比較
當時802.16 group 提議採SUI model, 原來此model是用在美國2.5GHz ~ 2.7GHz 的Multipoint Microwave Distribution System, 在SUI model中的計算參數有, AP與CPE天線間的距離, 因為樹及障礙物造成的shadow fading effect的調整因子, 基站離地表高度, 使用的載波頻率, CPE天線離地表的高度

Although the ECC-33 model is most appproximate to the real measurement in Urban area, yet the ECC-33 model is lack of the adjustment factor for suburban and rural area. Hence Cost 231-Hata model is used for the Suburban area performance evaluation in the WiMax released document Mobile_WiMax_Part1_Overview_and_Performance section 5.2 Mobile WiMax link budget.

WiMax QoS and Scheduling

Scheduling Services: 在Connection上傳送data時, MAC scheduler支援的資料處理機制, 可分為下列幾種排程服務

Unsolicited Grant Service (UGS): 用以支援在每一週期間隔會發出固定大小封包的即時資料流服務, 例如T1/E1, 無Silent Suppression的VoIP, 此種排程服務必須支援的QoS參數為: Max Sustained Traffic Rate, Max Latency, Tolerated Jitter, Req/Tx Policy, Min Reserved Traffic Rate(若有的話, 通常與Max Sustained Traffic Rate)
BS在固定週期間隔就會依據Service Flow的Max Sustained Traffic Rate的要求主動發Data Burst Grant IE給SS
此服務在Req/Tx Policy上必須禁止SS在此連線上採用connection request(爭奪請求)的機會

Real-time Polling Service (rtPS):用以支援在每一週期間隔會發出封包大小不定的即時資料流服務, 例如MPEG, 此種排程服務必須支援的QoS參數為: Min Reserved Traffic Rate, Max Sustained Traffic Rate, Max Latency, Req/Tx Policy, 此服務在Req/Tx Policy上也必須禁止SS在此連線上採用Connection Request的機會

Non-real-time Polling Service (nrtPS): 用以支援需要保證最小data rate且容許延遲(delay-tolerant)而封包大小不定的資料流, 例如FTP, 此種排程服務必須支援的QoS參數為: Min Reserved Traffic Rate, Max Sustained Traffic Rate, Traffic Priority, Req/Tx Policy

Best Effort (BE): 用以支援不需保證最少服務等級, 可以採用空閒時才處理的方式, 此種排程服務必須支援的QoS參數為: Max Sustained Traffic Rate, Traffic Priority, Req/Tx Policy

上述幾種排程服務中的QoS參數, 是透過DSA, DSC message對話所管理的
