Abstract :
In this paper, a simple method for generating correlated Rayleigh-fading envelopes with any desired correlation factor is proposed. In addition, based on a process of apparition and vanishing of same-delay correlated rays, a time-varying impulse response model of the indoor radio channel is developed with the aid of the proposed method. This proposal provides a straightforward tool for simulating the variant behavior of wireless channels.
