摘要

空时码解码算法往往假设信道状态信息(CSI)已经事先估计出

信道估计需要额外的运算量

而且信道估计误差使解码性能降低.本文提出一种基于子空间方法的空时分组码直接解码算法

利用空时分组码的结构

结合子空间算法

可以不需要信道信息

直接得到码符信息的闭式解.仿真实验结果表明

随着噪声子空间求解准确度的提高

直接解码算法性能逐渐接近使用确切信道信息的相关解码器.

Abstract

In recent work on decoding space-time codes

it is assumed that a channel estimate is obtained.To estimate the channel increases the computation load and a loss in performance of decoding is incurred by the error of channel estimate.In this paper

we propose a new decoding algorithm for space-time block coding.Combined with the structure of space-time block coding

the subspace of the transmitted signal are exploited to carry out the decoding without knowledge of the channel.Simulation results show that with the increase of the precision of noise subspace

the performance of our decoding algorithm approaches that of the coherent decoding algorithm with knowledge of channel.
