摘要

对于一种采用比特交织的随机分层结构的空时码

提出了一种应用Turbo原理的迭代检测—译码方法

新方法基于软干扰消除的BLAST检测和卷积码的SISO(softinputsoftoutput)译码

通过交换检测器和译码器之间的软信息

为迭代处理提供新的软信息。新方法大大提高了系统的性能

计算机仿真结果和计算复杂度分析显示了新方法的应用潜力。

Abstract

Based on one kind of layered space-time code which used bit-interleavered and random-layered model

a joint detection-decoding method based on the Turbo principle was proposed.The new method used soft-interference canceller and SISO decoder and improved the exchange of soft information between them.By iterative procession it improved the performance of the whole system.The potential practice capability is proved by simulation results and computational complexity analysis.
