空时分组码在不同衰落信道的仿真与分析

通过仿真验证了空时分组码的适用信道和其抗衰落性能。介绍了Almouti所提出的正交空时分组码的基本编译码原理,分别在高斯信道、瑞利信道和赖斯信道的状况下对其进行了仿真,并对结果进行了分析。总结了正交空时分组码在不同衰落信道中的性能,通过仿真试验说明空时分组码的适用信道是散射分量丰富的赖斯信道和瑞利信道。

Performance Simulation and Analysis of Space-time Block Coding under Different Fading Channels

This paper finds out the suitable channel and the performance under the different fading channels for the space-time coding through the simulation.It introduces the basic principle of the STBC(Space-Time Block Coding)presented by Almouti firstly,then makes the simulation under the Gauss channel,Rayleigh fading channel and the Rician channel respectively,and analyzes the simulation results.Finally,it summarizes the performance of the STBC under the different fading channels,explains that the adaptive channels of the STBC are those Rayleigh channel and Rician channel which including severely scatter.
