Abstract

Abstract:

When the transmitter or receiver moves fast, wireless radio channel for mobile communication system is non-stationary.This paper establishes a non-stationary Rice fading channel model with time evolution for the dynamic propagation link between mobile and base stations.A generation method is proposed for non-stationary fading channels based on the sum-of-linear-frequency-modulation (SoLFM) signals, and an algorithm for parameter updating designed.Experimental results show that the proposed method can ensure smooth handoff of fading channel states and continuity of fading amplitude and phase.It can also reproduce non-stationarity of a fading channel, and ensure the channel model's time-variant envelope distribution and time-variant Doppler power spectrum agree with the desired values.The model and its generation method can be applied to evaluate performance and validate a wireless mobile system in a time-variant propagation environment.

Key words: non-stationary fading, channel model, Doppler power spectrum, linear frequency modulation
