摘要

传统的准正交空时分组码可以实现全速率传输

但是不能获得最大的发送分集增益

而且译码复杂度相对较高

这主要是由于检测矩阵中存在干扰项造成的.为了解决这个问题

本文提出了一种新的准正交空时分组方案

该方案通过利用Givens旋转运算

将检测矩阵变换为一个对角阵

消除其中的干扰项

使得接收端可以采用线性方法来译码

从而既提高了系统的分集增益

又降低了译码的复杂度.仿真实验也验证了所提方案的优越性.

Abstract

A conventional QO-STBC scheme can achieve the full rate

but at the cost of transmission diversity gain and decoding complexity.These disadvantages of the conventional QO-STBC scheme are mainly a result of interference terms in the detection matrix.In order to solve the problem

this paper proposes a new QO-STBC scheme which transforms the original detection matrix into a diagonal matrix using Givens rotation algorithm and eliminates interference terms.The proposed method achieves improved diversi...
