摘　　要：该文通过仿真研究了V-BLAST与Turbo码结合的系统性能。已有的V-BLAST处理算法与Turbo码的解码是分别进行的,这样在接收端Turbo码的译码器没有充分利用接收信号的软信息。通过将V-BLAST与Turbo码译码有机地结合起来,实现并不复杂,但性能却有明显的提高。Through simulation this paper studies the performance of the system of V-BLAST combined with turbo code. The current methods process the V-BLAST algorithm and turbo decode algorithm independently. So it does not utilize the soft information of the received signal sufficiently. By simulation a novel method is presented. Through the combination of these two algorithms the complexity of the system realization does not increase, but the performance improves obviously.
