This block implements a basic fading model simulator that can be used to help evaluate, design, and test various signals, waveforms, and algorithms.

This algorithm implements the method described in

Parameters[edit]

(R): Run-time adjustable

Num Sinusoids (SoS model)
The number of sinusoids to use in simulating the channel; 8 is a good value
Normalized Max Doppler (fD*Ts) (R)
Normalized maximum Doppler frequency, fD * Ts
LOS Model
Include Line-of-Site path? selects between Rayleigh (NLOS) and Rician (LOS) models
Rician factor (K) (R)
Rician factor (ratio of the specular power to the scattered power)
Seed
Number to seed the noise generators
