MIMO-OFDM系统的性能分析

摘要
MIMO-OFDM无线通信在数字家庭有着广泛的应用。本文在Simulink平台上设计了一个MIMO-OFDM物理层无线通信系统,对其空时块编码、波速形成进行了系统仿真、验证与性能分析,得出了在不同SNR通信环境下最优的MCS模式选择。这为数字音频无线传输的FPGA工程实现提供了理论依据。
MIMO-OFDM is widely applied in digital households. This paper designs a physical layer of wireless communication system on the Simulink platform. The paper performs a system simulation, verification and performance analysis on its STBC module and beamforming module, and works out the optimal choices of MCS pattern under different SNR communication environments, which can provide theoretical foundation for the implementation of FPGA engineering with wireless audio transmission.
