You can use Matlab or Octave to examine the channel fading process that is stored int the output file rayleigh_test.it
. Try the followigh code to view a part of the fading process:
itload("rayleigh_test.it")
figure(1); clf;
semilogy(abs(ch_coeffs(1:200)))
Note: Make sure that the folder $PREFIX/share/itpp
is included your Matlab/Octave path variable ($PREFIX
is the IT++ installation prefix: /usr/local
by default).
