摘要

在传统的方案中

将准正交空时码(quasi-orthogonal space-time block codes)经过调制之后强行转换为酉空时码(unitaryspace-time codes)再进行差分编码.将调制方案进行改进

以使得码元之间的距离增大

以提高其编码增益

从而提高系统性能.与传统的准正交差分空时码相比

所提方案误码性能得以提高.

Abstract

In the traditional scheme

the modulated quasi-orthogonal space-time codes is transformed to be unitary space-time codes then the program of differential encoding could be constructed. Transforming the method of modulation

a new scheme is proposed to expand the code distance which could advance the codes diversity so as to enhance the performance. Compared with the traditional differential space-time codes

this scheme could increase the performance.
