We have considered QPSK modulation and a Rayleigh flat fading channel and perfect phase matching between the transmitter and the receiver. The fixed parameters used in the simulation are shown in Table 1. WebThe considered WiMax simulator consists of a burst generator, a channel, and a receiver. Simulations are carried over both Additive White Gaussian Noise (AWGN) and Rayleigh fading channel. In case of Rayleigh fading channel, the modulated signal is subject to zero mean and unit variance Rayleigh fading plus zero-mean AWGN noise. green bank class action lawsuit turbotax
