Sir, thank you for the code, however following error arises while running the code

[rajnigupta-555]

Error using comm.RayleighChannel/step
Changing the complexity (from real to complex) on input 1 of System object comm.RayleighChannel is not allowed without first calling
the release() method.

Error in Channel_functions/ApplyChannel (line 62)
y = step(rchan, X(:));

Error in Main_Simulation (line 49)
[ h, y ] = ch_func.ApplyChannel( rchan, xp_cp, K_cp); - Show complete stack trace

Dear @rajnigupta-555,

Thank you for reporting this and your interest in my research. The error is caused by a change in how System Objects handle input complexity in different MATLAB versions. I will update the ApplyChannel function to include a release(rchan) call or ensure consistent input types to resolve this. I'll post an update once the fix is pushed.

Best regards,
