空時差分編碼(Differential STBC) 是將傳統的空時區塊編碼(Space Time Block code, STBC)做類似Differential Coding 的操作，經此操作後形成的Differential STBC其特色是傳送端與接收端不需要知道通道的資訊(Channel state information)，依然可以實現完全空間分集(Full spatial diversity)。而完全互補碼分碼多工系統(CC-CDMA)係利用完全互補碼(Complete Complementary Codes)的自相關與互相關的優良特性，理想上可使系統達到MI-free與MAI-free。本篇論文我們試著將Differential STBC與CC-CDMA二種系統結合，並討論其整合後的特性。

Differential space time block coding is a technology that combining traditional space time block coding and differential coding. Differential space time block coding could exploit full spatial diversity gain where the channel state information is not known. Each user in CC-CDMA system is assigned a fold of codes which sent via different carriers to reconstruct perfect auto-correlation and cross-correlation function. Complete Complementary codes could offer MAI-free and MI-free operation for DS-spreading. In this thesis we combine differential space time block coding and CC-CDMA, and discuss the character of the system.
