Introduction We make the following assumptions Receiver knows channel characteristics but not transmitter. Ie: fast feedback link required otherwise. We allow changes to propagation environment to be slow in time scale compared to burst rate. Model used is Rayleigh fading. Use information theory to find out increase in bit/cycle compared to no of antennas used.

Introduction: Rayleigh fading Model useful when no LOS path exists. Zero mean Gaussian process. Can be used to model ionospheric and tropospheric scatters. If relative motion exists between TX and RX: fading is correlated
