WebSep 25, 2024 · The initial seed for the Rayleigh Fading Channel Block in SIMULINK is randomized to observe the significant improvement in BER. This is to ensure different Rayleigh Fading Channel Blocks are uncorrelated with each other. The models for three and five receiver antennas are shown in Figs. 5 and 6, respectively. Fig. 5. WebMay 27, 2024 · The double Rayleigh (or Rayleigh-product) model is a special case of the double-scattering model, where all three correlation matrices are equal to the identity matrix [ 15 ]. In contrast to rich-scattering, analytical performance assessment under double-scattering channels are relatively rare. In [ 16 ], authors have presented a performance ...

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. WebIt is observed that the BER for a Rayleigh fading channel is much higher than the BER for an AWGN channel. In fact, for Rayleigh fading, the BER curve is almost a straight line!!! Rayleigh Fading. Note: 1. The input EbNo to the function is in dB so it is converted into linear scale by 10^(EbNo/10). 2. Noise is added in a Rayleigh fading channel ...
