How to generate Rayleigh fading values in matlab???

• tag0 = 0;
• sco = [1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0];
• out0 = xor(tag0,sco);
• tag1 = 1;
• sc1 = [1 1 0 0 0 0 1 1 0 0 1 1 1 1 0 0];
• out1 = xor(tag1,sc1);
• tag2 = 1;
• sc2 = [1 0 0 1 0 1 1 0 1 0 0 1 0 1 1 0];
• out2 = xor(tag2,sc2);

• I want to generate rayleigh fading values after this point how do i generate that??
• Also, I was reading article online which had the syntax mentioned below:

• rayChan = comm.RayleighChannel('SampleRate', 10000, 'MaximumDopplerShift', 100)
• sig = j*ones(2000,1);
• rayChan
• rayChan =
• comm.RayleighChannel with properties:
• SampleRate: 10000
• PathDelays: 0
• AveragePathGains: 0
• NormalizePathGains: true
• MaximumDopplerShift: 100
• DopplerSpectrum: [1×1 struct]

I am not understanding the significance of this code in this siutation. I know further if i plot this it will be me power level signal versus sample number but, I am not sure if this is what I am looking for.

Kindly help me in this situation
