ASSIGNMENT
The Level Crossing Rate (LCR) and the Average Fade Duration (AFD) are two important parameters that characterize the dynamics of the channel. For Rayleigh fading signal,
Using above formulae, we can find the average fade durations for different threshold levels. Find the average fade duration for threshold levels ρ = 0.01, ρ = 0.1 and ρ = 1. Assume maximum Doppler frequency is 200 Hz. The task is to design a Rayleigh fading simulator in MATLAB using a frequency domain method described in the Figure 1. Confirm the level crossing rates and average fade durations of your simulated outputs waveforms agree with those obtained analytically. Turn in printouts of your source code, waveform samples, and other pertinent results.
