摘要(中)

在行動通訊的多天線技術中，相差空間調變一次只使用一根天線，並藉由選擇傳送天線來多傳額外的資料位元，且可避免前導(pilot)訊號的浪費。傳統的相差空間調變使用兩區塊的相差檢測器，其錯誤率與同調檢測的錯誤率有一段明顯的差距。因此，本文基於以前低複雜度之兩區塊相差空間檢測，提出多區塊相差檢測方法，使其錯誤率接近同調檢測的錯誤率，又能兼顧低複雜度要求。除了原本的MPSK訊號以外，我們還將低複雜度的多區塊相差檢測用於APSK訊號，但在此情形，無法使用原本的檢測式，因此我們提出新的檢測式子，隨著區塊增加，其錯誤率也可以接近同調檢測。

摘要(英)

Among various multi-antenna technologies of mobile communication, differential spatial modulation (DSM) is a multi-antenna technique that uses only one antenna to transmit signals at a time and avoids pilot overhead. Traditional DSM uses a two-block differential detector, and its error rate is significantly different from that of coherent detection. Based on the existing low-complexity two-block differential detection, the thesis proposes a multiple block differential detection method, and makes its error rate close to the error rate of coherent detection, while taking into account the low complexity requirements. In addition to the original MPSK signal, we also use low-complexity multiple block detection for APSK signal, but in this case, the original detection formula cannot be used, so we propose a new detection formula. As the block length increases, its error rate can approach coherent detection.
