| Abstract: | The time selection and frequency selection of multi-path fading channels are analyzed in this paper.The multi-path effect and Doppler effect on channels are discussed and compared.Simulation analysis is done from the angle of the time domain and frequency domain respectively.To the time invariant and time variant multi-path fading channels,simulation results show the variation rate of signal is proportional to the increase of the time domain spread and the frequency domain spread. |
