    • 本篇論文，我們提出兩種方法來增加廣義相差空間調變的多樣性。第一種是使用4×4空時區塊碼的廣義相差空間調變，第二種方法是將區塊編碼調變結合廣義相差空間調變和使用複數天線矩陣。為了使廣義相差空間調變有更高的傳送速率，我們將交錯樣式加入廣義相差空間調變，研究和設計符合傳送多樣性為4的交錯樣式。最後我們比較這兩種方法，使用第二種方法的傳送速率會高於第一種方法，而第二種方法的錯誤率也優於第一種方法。

    In this thesis, we propose two schemes to increase the transmit diversity of generalized differential spatial modulation(GDSM). In the first scheme, a 4×4 space-time block code is used in GDSM. In the second schemes, block code modulation is concatenated with GDSM. To increase the transmission rate of GDSM, symbol interleaving is used. We design interleaving patterns of transmit diversity four. Finally, we compare these two schemes, and find that the transmission rate and the error rate of the second scheme are higher than those of the first one.
