I am trying to do a PLC simulation system, but my problem is in GMSK demodulator, in my simulation in Simulink MatLAB my output signal is very different from the input signal, below the model:

Below the block parameters:

I start doing this simulation yesterday, the values of each block is the default, and even without de AWGN block the error still appears. Someone knows what is happening?

That’s is because of the delay in the GMSK demodulator. MATLab GMSK demodulator uses Virtebi algorithm. You should delay the Rx BER in order to get back the correct data alignment.
