Simulation on Multi-path Fading in Wireless Channel

The wireless channel has characteristics of multi-path fading effect and time-varying in the mobile communication. Among them the multi-path fading effect is quite large for the performance of the system. Because the transmission environment is very complex, we use digital signal process to analyze propagation characteristic in wireless channel through MATLAB. This paper is mainly discussed several typical fading which are simulated using frequency transform methods through the computer. The performance of the multi-path fading channel in the mobile communication is studied by comparing BER, constellation map and eye-diagram. According to the different power of the multi-path signals, the simulations of different fading types and depths have been conducted.
