摘要

为了分析多输入多输出（MIMO）空时编码技术在不同信道条件下的性能优劣

研究了无线信道的衰落统计特性

对比了在Rayleigh信道、Rician信道和Nakagami信道条件下

正交频分复用空时块编码（STBC-OFDM）、垂直空时分层码（V-BLAST）及空时格型码（STTC）的系统误码率。通过仿真分析结果表明:STBC-OFDM系统在衰减指数为5的Nakagami信道条件

系统误码率最低

Rician信道次之

Rayleigh信道最高

而且当系统误码率为10-3时

其所需的信噪比（SNR）分别为7

11 d B;但对于V-BLAST和STTC系统

随着信噪比的增加

不同的信道条件对系统误码率的影响各有优劣。

Abstract

To analyze performance advantages and disadvantages of multi-input multi-output（ MIMO） space-time coding technique in different channel conditions

study fading statistics characteristics radio channel

compare system bit error rate（ BER） of orthogonal frequency division multiplexing space-time block coding（ STBCOFDM）

vertically layered space-time code（ V-BLAST） and space-time trellis code（ STTC） in the Rayleigh channel

Rician channel and Nakagami channel. Simulation analysis results show that STBC-OFDM system in Nakagami channel conditions whoses decay index is 5

BER is the lowest

Rician channel followed

Rayleigh channel is the highest

and when BER of system is 0. 001

its required SNR is 7

11 d B; and for V-BLAST and STTC systems

with signal noise ratio（ SNR） increasing

effects of different conditions of channel on BER of system are advantages and disadvantages.
