Improved Models for the Generation of Multiple Uncorrelated Rayleigh Fading Waveforms
An improved sum-of-sinusoids simulation model is proposed for Rayleigh fading channels. the new model employs random initial phase, and conditional random Doppler frequency for all individual sinusoids. the second-order statistics of the new simulator match the desired ones exactly even if the number of sinusoids is a single-digit integer. Other key statistics of the new simulator approach the desired ones of Clarke''s (1968) reference model as the number of sinusoids approaches infinity, while good convergence is achieved when the number of sinusoids is small. Moreover, the new simulator can be directly used to generate multiple uncorrelated fading waveforms; it is also pointed out that a class of 16 different simulators, which have identical statistical properties, can be developed for Rayleigh fading channels.
