Abstract:	相差空間調變是一種一次只使用一根天線傳送訊號的多天線技術，藉由選擇傳送天線可以多傳額外的資料位元，並避免前導(pilot)訊號的浪費。而當相差空間調變延伸為廣義相差空間調變時，每次傳輸則會使用多於一根的傳送天線，然而，現有的廣義相差空間調變的傳輸速率相當低。在本論文中，我們提出了新的廣義相差空間調變的方案，在相差空時調變上使用了符元交錯，我們同時也會提出有效的交錯樣式的特性和個數。藉由選擇廣義相差空間調變的交錯樣式，我們提出的方法可以擁有比現有的差空間調變更高的資料傳輸速率。 ;Differential spatial modulation (DSM) is a multi-antenna technique that uses only one antenna to transmit signals at a time and avoids pilot overhead. By selecting the transmitting antenna, additional data bits can be transmitted.DSM is extended to generalized DSM (GDSM) where more than one transmit antennas are activated each time. However, the transmission rate of the existing GDSM scheme is low. In this thesis, we propose a new GDSM scheme that uses symbol interleaving on differential space-time modulation. Properties and the number of valid interleaving patterns are shown as well. By selecting the interleaving patterns, the proposed scheme has higher data rates than the existing GDSM scheme.
