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.
WebThe block-fading channel [1], [2] is a useful channel model for a class of slowly-varying wireless communication chan-nels. The model is particularly relevant for delay-constraint applications where channel usage is restricted to only include a finite number of distinct channel blocks, each subject to independent flat fading. bingham medical centre binghamWebalong with the approximations of [1] and [2] in Figure 4. For the flat Rayleigh block fading channel simulations, the mean is set to zero, i.e. µH = 0, and the variance of the channel is set to unity, i.e. σ2 H = 1.
