中文摘要
本論文主要是以整合空時區塊碼(Space-Time Block Code, STBC)與互補碼(Complementary Code)分碼多工(Code Division Multiple Access, CDMA)系統為主要內容。我們所提出的整合系統除了保有互補碼本身的特性外(完美的自相關性與完美的互相關性)還可額外得到空時區塊碼所提供的傳送多重性(transmit diversity)。特別是在不同頻率上通道增益具有高度相關的情況下互補碼能夠發揮出干擾消除的優點。
我們也提出許多效能突破的方案。於接收端使用特殊的濾波器,如ZF濾波器、Turbo濾波器,輔助互補碼達到干擾消除的功效。
Abstract
This thesis mainly focuses on the integration of Space-Time Block Coding (STBC) and Complementary Code based CDMA system. Our proposed integration systems have not only the merit of complementary code but also the extra advantage of diversity gain from STBC. Especially, when the different frequency channel gain has strong correlation, the complementary code will cancel most of interference.
We also present a lot of improved structures for our proposed systems. We utilize special filters in receiver such as Zero-Forcing filter and Turbo Filter to assist complementary code in canceling interference.
