An algorithm for generating nonuniformly spaced correlated samples for simulating a nonselective Rayleigh fading channel

A nonselective Rayleigh fading channel model using a time-variant complex multiplier z(t) is considered. Performing a Monte Carlo simulation of this channel requires samples of z( t) with appropriate correlation (fading power spectrum). For an important f^-4 spectrum, there is a simple digital implementation that generates uniformly spaced samples. However, many communications systems have faded signals which appear only intermittently at the receiver. Nonuniformly spaced samples are better suited to a simulation of this situation. The author presents an algorithm for efficiently generating nonuniformly spaced correlated samples which have a specified f^-4 power spectrum
