Hello,
I want to simulate DBPSK modulation in AWGN channel using convolutional encoder and Viterbi decoder. I built the model in Simulink for hard decision of Viterbi decoder and it is working Ok. Now, I am trying to do the soft decision decoding, but I can't get the correct answer and BER is about 0.5. I used the quantization for the input of the Viterbi decoder. Can anyone help me to correct my model? I really appreciate your help.
