Detailed Description

fading simulator

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

Build the channel simulator.

Parameters:

N	The number of sinusiods to use in simulating the channel; 8 is a good value
fDTs	normalized maximum Doppler frequency, fD * Ts
LOS	include Line-of-Site path? selects between Rayleigh (NLOS) and Rician (LOS) models
K	Rician factor (ratio of the specular power to the scattered power)
seed	a random number to seed the noise generators
delays	A vector of values the specify the time delay of each impulse
mags	A vector of values that specifies the magnitude of each impulse
ntaps	The number of filter taps.
