The berfading function returns the bit error rate (BER) and symbol error rate (SER) over a Rayleigh or Rician fading channel for uncoded data using a specified modulation scheme. The first input argument, EbNo, is the energy per bit to noise power spectral density ratio (Eb/N0) in dB. ...
With an improved Rayleigh fading model and a zero-mean stochastic sinusoid as the scattering and specular components respectively, a stochastic simulation model is proposed for the generation of Rayleigh and Rician fading waveforms. Compared with the existing stochastic models, the proposed simulator need...
