Abstract

This paper introduces an improved method to generate multiple uncorrelated Rayleigh fading waveforms. Correlated waveforms occur occasionally when Generalized Method of Exact Doppler Spread is used. Detailed study shows how this error occurs and how to avoid it with the introduced parameter computation method. Moreover, a design concept of Set Partition is used to reduce the number of sinusoids needed in Sum-of-Sinusoids (SoS) method. Finally, performance analysis and comparisons are done to demonstrate the accuracy and efficiency of the improved method.
