Abstract:	本學位論文主要討論三個主題：空間最佳接收機之設計，基於增益轉傳型中繼網路之最高訊雜比分集結合技術和非同調區塊碼研究。三項主題均為處理在接收機未能取得完美的通道狀態資訊情形下，如何降低接收端之誤碼率。在第二章中，提出了一種新技術，用於在空間相關的複數型中上分佈(Nakagami-m)衰落通道(fading channel)上，藉由分集合成技術，可將接收訊號在不完美的通道狀態信息考量下完成分集結合。第三章研究了由增益轉傳(amplify-and-forward, AF)中繼網路(relay network)中，目的地節點只能獲得量化的通道狀態時所能獲致最高訊雜比分集合成（maximal-ratio combining, MRC）接收效能。在第四章中我們研究了NBC-TAPSK (noncoherent block-coded twisted-amplitude and phase-shift keying) 設計理念，雖然沒有相位的資訊，由模擬與分析的結果，NBC-8TAPSK非同調區塊碼技術使用與較低的複雜度，且能達成較低的誤碼率。;Three topics are studied in this dissertation: (1) a spatial optimum receiver, (2) amplify-and-forward relay networks, and (3) noncoherent block codes. All of them work with imperfect channel state information (CSI). Chapter 2 proposes a novel technique to facilitate diversity combining reception with imperfect channel state information (CSI) over spatially correlated complex-valued Nakagami-m fading channels. Chapter 3 studies an amplify-and-forward (AF) relay network while considering the impact of the quantization of the source-to-relay (SR) CSI. Chapter 4 studies a three-layer noncoherent block-coded twisted amplitude- and phase-shift keying (NBC-TAPSK) scheme. Simulation results confirm that the NBC-TAPSK detector outperforms the detector for the pilot-training-based coherent scheme and that NBC-8TAPSK offers better error performance than NBC-8PSK.
