correlated rayleigh fast fading

Did anyone generate a correlated Rayleigh fading channel in research the receiver diversity? To generate a Rayleigh fading channel, one could first design a FIR/IIR filter to have the desired spectrum property, then let a white Gaussin noise pass through the filter. To generate a correlated Rayleigh fading channel, one need at least to generate two independnet Rayleigh fading channels, then uses a matrix to introduce the correlations between the channels. How to design the matrix, eigen-decompositon or Chorlesky decomposition?

generate correlated fast fading

hi spweda:

... please take a look to this papers:

"Modelling Frequency Correlation of Fast Fading in Frequency Hopping GSM Link Simulations"
Klingenbrunn, T. and Mogensen P.
IEEE VTC 1999, pp. 2398-2402

"Generation of Correlated Rayleigh Fading Envelopes for Spread Spectrum Applications"
Natarajan, B. et al
IEEE Comm. Letters 2000, pp. 9-11

...I'm very interested, please PM me if you implement it

Best Regards

correlated fading simulation

Hi, Minhawk

Thanks for your references. I have implemented the Correlated Rayleigh fading channel based on the second reference. The Cholesky decomposition was used in the reference.
