Abstract :
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 chained simulation realizations are presented and commented on
