This matlab program describes the Nakagami Fading coefficient generation for a Nakagami Fading Channel. The matlab program is written in a clear way and it produces the corresponding simulation result. The same way can be applied for Rayleigh and Rician fading coefficient generation for Rayleigh and Rician fading channels.
