Analysis of Wireless Channel Characteristic in Coal Mine

He Wei

Abstract

In this paper,mine multipath rayleigh fading channel and surface additive white Gaussian noise channel,rician fading channels.By using the MATLAB simulation software on different channels QPSK BER analysis and simulation of communication systems,came to the mine under multipath Rayleigh fading channel error rate is higher than the surface of additive white gaussian noise channel and rician fading channels,conclusions and seriously reduce the performance of communication systems.
