Rayleigh vs rician
WebRayleigh/ Rician mixed fading channels are considered to model alternately the multicast/ eavesdropper and eavesdropper/ multicast channels as such mixed fading scenarios are often encountered in cellular communication where only one link (either multicast or eavesdropper) undergo a line-of-sight propagation path. WebMar 2, 2024 · Under these assumptions, the magnitude of the channel coefficient is Rice/Rician distributed, which is why it is called Rician fading. More precisely, , which depends on the magnitude and the variance of the scattering. Interestingly, the distribution does not depend on the phase , because the magnitude removes phases and and are …

WebFinally, we compared the performance of MRC and OC in the presence of channel estimation errors with multiple interferers over Rayleigh fading channels when the system is interference-limited. We discovered that in the presence of channel estimation errors MRC can outperform OC, especially for small values of the correlation coefficient. Moreover, as … WebJan 16, 2006 · These results are derived using a different approach than the one used by Telatar for the i.i.d. Rayleigh case. The complementary cumulative distribution function (CCDF) of the MI is also obtained using a Gaussian approximation. The CDF of MI can serve as an upper bound to the outage probability of nonergodic MIMO Rician channels.
