**rayleigh fading matlab**

Hi all,

I have got a Rayleigh Fading Channel Simulation code by Matlab.

The code list below:

% Rayleigh fading

a = sqrt(0.5)*( randn( 1, symbols_per_frame) + j*randn( 1, symbols_per_frame) );

% complex noise

noise = sqrt(variance)*( randn(1,symbols_per_frame) + j*randn(1,symbols_per_frame) );

% in all

code_fade = a.*code + noise;

Is the code right? If not right, how to modify it?

Best regards,

Davy
