GQR models for directional wireless channels

In this paper novel reduced complexity statistical models for the representation of wide sense stationary-uncorrelated scattering directional wireless channels affected by Rayleigh fading are developed. Their derivation is based on the so-called Gaussian quadrature rule approach illustrated in E Chiavaccini et al. (2001). for non directional channels. Numerical results evidence that the proposed models can provide a simple and accurate stochastic representation of directional fading channels.
