fD=12; %Doppler frequency in Hz
ts= 5.0000e-04; %sampling time in seconds (1/2000)
fs=2000; %sampling frequency
pathDelays=[0 0.1 1 5 10 15 20].*1e-6; % delay for the three paths is seconds
avgPathGains=[0, -2, -3, -10, -15, -18, -20]; % average path gains in each of the three paths in dB
rchan = comm.RayleighChannel('SampleRate',fs, ...
'PathDelays',pathDelays,'AveragePathGains',avgPathGains, ...
'MaximumDopplerShift',fD,'FadingTechnique','Sum of sinusoids'); %Rayleigh channel
faded_signal=filter(rchan,modulated_signal); %Tx signal passing through channel
