Abstract
An application of importance sampling to reducing the run times of Monte Carlo simulations is described. It contains two contributions. First is a demonstration that biasing the simulation program to produce more fades can reduce the variance of the estimates of the BER. Second is an efficient method for creating channel gain sequences associated with fades, according to an arbitrarily specified fading spectrum
