EB/N0 VS BER FOR BPSK OVER RICIAN FADING CHANNEL

WebJul 7, 2024 · Rician fading or Ricean fading is a stochastic model for radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by several different paths (hence exhibiting multipath interference), and at least one of the paths is changing (lengthening or shortening). 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. WebApr 6, 2024 · Hi Ankita, Rician channel is very similar to Rayleigh fading channel, except for the presence of LOS path Usually we model Rayleigh fading coefficients as h = x + i*y, where, x and y are zero mean, gaussian random variables. In the case of Ricean fading also, we model h as, h = x + i*y. diaper cakes for boys directions
