Wireless fading vector channel model for multi-antenna system at mobile terminals

To investigate the performance of smart antenna technology applied in mobile terminals, the simulation of multi-antenna system requires a spatial channel model, which should reasonably characterize the effects of wireless channel, such as time-varying, multipath-fading and Doppler effects, between base station and mobile handsets. This paper presents a space-time vector channel model fit for these demands. Based on the lowpass-equivalent impulse response, the diverse stochastic parameters of the channel, such as DOA/TOA and Rayleigh fading, are discussed at full length. The final simulated channel data produced by this model is consistent with previous theory and measurement, which exhibits its feasibility for the further investigation of different smart antenna algorithms or joint detection techniques.
