摘　　要：空时码技术可以提高数据的传输速率、频谱利用率和传输质量,在无线通信系统中得到了广泛的关注和研究。基于此对MIMO-OFDM系统中空时码的误码性能进行了研究和分析。在瑞利衰落信道下,比较了Alam-outi码和V-BLAST码的误码性能,以及联合Turbo码的空时码系统的性能。Space-time code techniques have been widely studied in wireless communication systems for they can improve the data rate,spectrum efficiency and provide better QoS.This paper makes research on the performance of error-bit in MIMO-OFDM systems.In Rayleigh channel,the performance of Alamouti code and V-BLAST code is investigated,as well as combined with turbo code.

关 键 词：空时码 MIMO-OFDM TURBO码
