Rayleigh block fading
The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … WebThe performance of MIMO system can be improved by using multiple antennas at transmitting and receiving side to provide spatial diversity. In this paper, the effects of the number of transmit and receive antennas on the performance of MIMO system over AWGN and Rayleigh fading channels with ZF receiver is analyzed.
