Abstract

In this paper, we present a new, computationally efficient simulator for time-varying multi-path (fast fading) vector channel that can be used to evaluate the performance of antenna array wireless receivers. The development of the simulator is based on the emulation of the spatio-temporal correlation properties of the vector channel. The channel is modeled as a multi-channel FIR system with time-varying coefficients which are obtained via the application of a space-time correlation shaping transformation on some independent random sequences. The various parts of the new simulator are detailed and channel simulation realizations are presented and commented. 1 INTRODUCTION Because of the limited availability of spectrum, wireless system designers are under pressure to achieve high spectral efficiency. To this end, future wireless systems will almost certainly use adaptive antenna arrays [1]. Since performance analysis of communication systems is often done first via computer simulations...
