| 摘 要： | 为满足采用不同调制方式和空时编码类型的MIMO(Multiple Input Multiple Output)通信的性能分析需求,在深入研究MIMO通信机理和空时编译码机理基础上,基于MATLAB/GUI软件环境进行MIMO通信仿真软件设计,实现了对不同参数条件下MIMO通信系统性能分析的可视化、可交互性。仿真结果表明DBLAST(Diagonal Bell-Labs Layered Space-Time)在4FSK(Frequency Shift Keying)和QPSK(Quadrature Phase Shift Keying)调制方式下性能较优,利用设计的仿真软件可对MIMO通信的参数优化配置提供指导。

Design and Implementation of MIMO Communication Simulation Software Based on MATLAB GUI |
| |
| Abstract: | In order to meet with performance analysis needs of MIMO communication using different modulation mode and space-time coding type,on the basis of further research of MIMO communication mechanism and space -time coding -decoding mechanism,MIMO communication simulation software based on MATLAB/GUI software environment is designed. Further,visualization and interoperability of MIMO communication system performance analysis is realized under the different parameters. Simulation result shows that the performance of DBLAST using 4FSK and QPSK modulation is better,and using the designed simulation software can provide guidance to optimize parameters configuration of MIMO communication. |
