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
