Abstract

In this paper, we present a new computationally efficient time-varying multi-path vectorial channel simulator that can be used to evaluate the performance of antenna array wireless receivers challenged by fast fading. 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 described and channel simulation realizations are presented and commented. 1. INTRODUCTION Future wireless systems will almost certainly use adaptive antenna arrays [1] to increase capacity. An effective multi-path vector (multi-antenna) channel simulator is required for the performance analysis of communication systems via computer. The design of such a simulator must be done with great care si...
