Hi,
You can create Rician fading channel system object using comm.RicianChannel and use info method on the system object created to obtain the channel coefficients as shown below.
ricianChan = comm.RicianChannel('SampleRate',fs, ...
'PathDelays',pathDelays, ...
'AveragePathGains',avgPathGains, ...
'KFactor',10,'MaximumDopplerShift',fD);
Info=info(ricianChan);
ChanCoeff=Info.ChannelFilterCoefficients;
