本篇論文係研究在放大後傳送(amplify-and-forward, AF) 合作式系統裡面, 將結合
通道估測與資料檢測機制應用於接收端設計上; 另外, 本篇論文亦探討適用此系統的非線
性區塊碼的碼簿建構方式。此論文的合作式系統考慮接收端的接收訊號會受到多重路徑
的影響, 且假設接收端未知通道係數資訊, 引入結合通道估測與資料檢測方法解碼, 並透
過編碼機制的限制, 使系統達到全散度(full diversity) 的特性。最後會探討適用此系統
模式的編碼策略, 引入已知的近似方法來逼近資料錯誤率, 取之為上限值做為編碼策略,
做為模擬退火演算法的依據, 產生適用於此合作式系統的非線性區塊碼。最後的數值模
擬將驗證此機制下產生的碼簿可達到全散度增益(full diversity gain) , 且比較將設計的
碼簿應用於此系統的資料錯誤率會優於其他解碼機制。

In this thesis, the problem of data transmission in amplify-and-forward (AF) co-
operative system which implemented joint channel estimation and data detection at
the destination (receiver) is considered. The nonlinear block code is designed to as-
sist the above methodology. The design criterion takes into account the uncertainty
of channel parameters at the receiver based on joint channel estimation and data
detection algorithm and the simulations will prove that it can achieve full diversity
that is offered by multiple relay and frequency-selective fading channel. Using an
approximation of the union boun on the error probability as the design criterion,
such that it can be simulated as a function for simulated annealing algorithm. The
designed codewords are applied to the AF cooperative system. In order to assess
the performance of joint estimation and detection fashion, the numerical simulations
will be carried out the word error rate (WER) performances illustrate that improve-
ment over differnt benchmark schemes can be obtained.
