Fading Model

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

(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

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
