空时分组码的多径译码方法

Multipath Space-Time Block Decoding Method in CDMA System

摘要:

为有效地将空时分组码应用到多径衰落环境下的码分多址系统，以充分利用多个路径的信号能量，提出了一种多径环境下空时分组码译码的新方法。由于空时分组码译码与信道估计紧密相关，本文亦讨论了多径信道估计以及信道估计误差对本方法的影响。仿真结果表明，采用多路径译码方法可明显提高系统的误码率性能。

Abstract:

For applying STBC(Space-Time Block Codes) to CDMA(Code Division Multiple Access) system in the multipath fading environment effectively,a method of multipath space-time block decoding is presented to collect the multipath signal energy adequately.Because
