摘要

为获得存在多径衰落的MIMO-OFDM系统中高速率传输方案

给出了一种基于线形星座预编码和坐标交织的速率为1的简单空时频分组码.该传输方案通过线性星座预编码来获得频率分集增益

通过坐标交织变换来获得传输速率为1

且能适当改善系统的误码性能.仿真结果表明

与传统的结合空时码的OFDM系统相比

该方案能获得更大的分集增益、更高的频谱效率和更好的误码性能.在误码率为10

-2

的未加信道编码的条件

本文方案与传统方案相比

至少能够提供约4dB的性能增益.若在接收端采用MMSE等线性接收方案

本文方案的计算复杂度并没有明显的增加.

Abstract

To getting high data rate tramscnission scheme in a mufti-path fading environment in Multiple Input Multiple Out-put(MIMO)-Orthogonal Frequency Division Multiplexing(OFDM) systems

a simple rate-one Space-Time-Frequency Block Code(STFBC) based on linear constellation decoding(LCP) and coordinate interleaving is proposed.The proposed scheme can get the frequency diversity gain by applying LCP transform and reach transmission rate one by applying coordinate interleaving to the LCP transfomed symbols

and the proposed scheme can improve the bit error petformance of the systems.Simulation show that compared with the traditional Space-Timc-OFDM(ST-OFDM) system

arr scheme can get mote diversity gain

more high frequency efficiency and better bit error performance.Without channel coding

when the BER is 10

-2

our scheme artperforms the traditional scheme about 4dB.If adopting such as MMSE linear receive scheme at the cereiver

the computing complexity of the proposed sctrecne does not increase in evidence.
