Generation of correlated Rayleigh fading envelopes for spread spectrum applications
Balasubramaniam Natarajan, C.R. Nassar, Vikram Chandrasekhar · IEEE Communications Letters · 2000
A procedure for generating N Rayleigh fading envelopes with any desired covariance matrix is given. This method, numerical in nature, enables researchers to simulate correlated fading envelopes, for use in: (1) the study of the impact of correlation on diversity system performance and (2) the study of multicarrier CDMA (MC-CDMA), where the number of carriers notably exceeds the degree of system diversity.
