I'm using the Rayleigh Channel in Simulink but I can't calculate the BER. I always get values near to 0.5 which doesn't make sense (even using high EbNo values). [In this simulink model] I found a trick to calculate the BER but I also would like to use delays and attenuation vectors.
Any idea of how to calculate the BER? I have tried also with a Matlab script comparing bit to bit but I also get values near 0.5.
Edit1: I can calculate the BER but it is always around 0.5, regardless EbNo values. I'm using this simulink model.
Edit2: I'm using delay and attenuation vector so I have problems with the array dimensions:
