tHIS MATLAB CODE SIMULATE RAYLEIGH MODEL USED IN WIRELESS COMMUNICATION SYSTEMS.Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communications channel) will vary randomly, or fade, according to a Rayleigh distribution.

This model demonstrates a DC-AC converter. 3 leg Mosfet operated inverter is constructed . Can be used to demonstrate the relationship of input DC, output voltage, modulation index , filter selection and switching frequency. 3rd harmonic injection features
