How can I create an instance of a rayleigh channel using comm.RayleighChannel? I would like to give the number of path delays and corresponding path gains to generat a channel coefficient WITHOUT passing a signal through it. Earlier, this was possible using the below code:

H = rayleighchan(ts,doppler,PathDelays, AvgPathGains);

But I'm unable to do it using comm.RayleighChannel. Please help.

Thanks!

Hi Mia,

I understand you wish to create a rayleigh channel using comm.RayleighChannel. Please find below an example to do so. Here some test values are assumed for this particular example.

rayleighchan = comm.RayleighChannel( ...

'SampleRate',10e3, ...

'PathDelays',[0 1.5e-4], ...

'AveragePathGains',[2 3], ...

'NormalizePathGains',true, ...

'MaximumDopplerShift',30, ...

'DopplerSpectrum',{doppler('Gaussian',0.6),doppler('Flat')}, ...

'RandomStream','mt19937ar with seed', ...

'Seed',22, ...

'PathGainsOutputPort',true)

rayleighchan =

comm.RayleighChannel with properties: SampleRate: 10000 PathDelays: [0 1.5000e-04] AveragePathGains: [2 3] NormalizePathGains: true MaximumDopplerShift: 30 DopplerSpectrum: {[1×1 struct] [1×1 struct]} ChannelFiltering: true PathGainsOutputPort: true Show all properties
