Abstract:

© 1997-2012 IEEE. Generating Rayleigh fading is a well investigated subject. However, most existing methods are fundamentally based on a sum-of-sinusoids, hence have a high computational complexity and become impractical when modelling massive MIMO systems. In this letter we present a novel recursive complex number multiplication method to generate Rayleigh fading for discrete signals. The computational complexity of the method is 75-94% less than all prominent sum-of-sinusoid methods. It also preserves the theoretically expected Bessel autocorrelation of a fading channel, zero cross-correlation between different fading channels and the power spectral density.
