Research and Simulation of Propagation Characteristic in Wireless Channel

According to the complexity and randomness of transmission environment, using digital signal process to analyse propagation characteristic in wireless channel through MATLAB. The free space fading, the multipath delay and the maximum Doppler frequency offset are must be considered in terms of the wireless channel´s characteristics. In simulation people often has an assumption that the channel is a slow fading channel. This paper is mainly discussed several typical fadings which are simulated using frequency transform methods through the computer. In the end the bit error rate figure and the channel transmission function figure are analysed. The conclusion can be used to set up the base station in mobile service areas and how to develop the signal transmission rate.
