Abstract: In modern wireless communication system, communication channel is a major part. The communication quality is very important when the signal is transmitted in the channel. Doppler shift, path fading and multipath delay have great influence on communication quality. This paper analyzes the fading characteristics of wireless communication channel. Large scale fading and small scale fading are two kinds of fading that affect wireless communication. Matlab software is used to model and analyze the two kinds of fading, which is of great significance to the wireless propagation characteristics of signals in complex environment. Through theoretical research and analysis, simulation software is used to simulate Rayleigh fading while Jakes and Clarke models are analyzed. At the same time, the large-scale fading model which affects free space communication is simulated and analyzed.

Key words: MATLAB simulation, wireless channel, large-scale fading, small-scale fading, feature decline
