WebAug 28, 2024 · The Rayleigh channel class (rayleighchan) generates non-LOS multi-path channels that are characterized by Rayleigh fading. The variables PathDelays are the excess delays due to each multi-path component, where each path has an amplitude that is Rayleigh distributed, and phase that is uniformly distributed. Webchan = rayleighchan(ts,fd,tau,pdb) constructs a frequency-selective ("multiple path") fading channel object that models each discrete path as an independent Rayleigh fading process. tau is a vector of path delays, each specified in seconds. pdb is a vector of average path gains, each specified in dB.
