    • 在本論文中，我們研究兩種空間調變。第一種是長區塊相差空間調變，原始長區塊相差空間調變的解碼會過於複雜，因此本篇論文提出了新的位元映射和檢測方式以降低長區塊相差空間調變的解碼複雜度。第二種是廣義空間調變，為了使廣義空間調變有更高的傳送速率，我們將交錯樣式加入廣義空間調變，我們先是分類不同的天線排列，並推導出每一種類適合的交錯樣式，使得傳送多樣性至少為二。最後，我們將廣義相差空間調變套用於長區塊相差空間調變的系統架構。與原本的廣義相差空間調變相比，所提出的方案有更高的傳輸速率，且在接收天線等同傳送天線的情況下，隨著區塊長度的增加，新方案會有更好的錯誤率。

    In this thesis, we research two kinds of spatial modulation. The first one is long block differential spatial modulation (LB-DSM). The decoding of the original LB-DSM is too complicated, so we propose a new bit mapping and detection method to reduce the decoding complexity of the LB-DSM. The second is generalized spatial modulation (GSM). We first classify different antenna permutation and derive the appropriate interleaving patterns for each class, so that the transmission diversity is at least two. Finally, we apply the scheme of LB-DSM to the generalized differential spatial modulation (GDSM), called LB-DSM. The LB-DSM has a higher transmission rate than the GDSM with symbol interleaved. The new scheme has a better error rate with increasing transmission block length when the receiving antenna is equivalent to the transmitting antenna.
