WebWhen there is a dominant stationary (nonfading) signal component present, such as a line-of-sight propagation path, the small-scale fading envelope distribution is Ricean. In such a situation, random multipath components arriving at different angles are superimposed on a stationary dominant signal. WebIn this letter, a class of new sum-of-sinusoids statistical simulation models is proposed for Rayleigh fading channels which may contain multiple uncorrelated faders. It is shown that the new Rayleigh fading channel models have the desired statistical properties even when the number of sinusoids is small.

"WebTo generate a Rayleigh fading channel in Python we need to first specify the max Doppler shift, in Hz, which is based on how fast the transmitter and/or receiver is moving, denoted . When the velocity is small compared to the speed of light, which will always be the case in wireless communications, the Doppler shift can be calculated as: " - Small scale rayleigh fading

WebWhen the bandwidth is too small for the signal to resolve the individual components, the frequency response is approximately flat because of the minimal time dispersion caused by the multipath channel. This kind of multipath fading is often referred to as narrowband fading, or frequency-flat fading.
