How to generate Rayleigh fading channel in Matlab?

Create Rayleigh Channel Using Independent Doppler Spectrum

Change the default Jakes Doppler spectrum of a configured three-path Rayleigh channel object to a cell array of different Doppler spectra, and then change the properties of the Doppler spectrum of the third path.

How do you calculate channel coefficient?

In your definition of the SINR, h is the channel coefficient. What it means is this: if we send a signal x(t) and model our channel as stationary and frequency-flat then the signal we receive is y(t)=h⋅x(t) (plus noise) so that its power is Py=E|y|2=|h|2⋅Px.

What is BER performance in fading channels?

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 (E_b/N₀) in dB.
