    • 本論文探討在多重收發天線系統中的自動要求重傳機制(automatic repeat request, ARQ)，考慮結合貝爾實驗室層次空時(Bell Labs layered space-time, BLAST)架構和空時區塊碼(space-time block codes, STBC)架構之自動要求重傳機制。我們提出一種較低複雜度架構，藉由Chase 演算法得到幾個測試樣式(test pattern)，以達到部分錯誤更正，使得資料速率提高。在相近或較高的未偵測錯誤率和傳統自動要求重傳比較，我們所提出的架構之資料速率(throughput)提升，只付出解碼複雜度些微地增加。

    In this thesis, we discuss the automatic repeat request (ARQ) technique that combine the Bell Labs layered space time (BLAST) and the space time block codes (STBC) in the MIMO communication system. We also propose a low complexity scheme that gets several test patterns by the Chase algorithm to improve the throughput and corrects partial errors. Compared with the traditional ARQ scheme which has similar or higher undetected error rate, the throughput of our proposed system is increased with the price of slightly increased decoding complexity.
