Hi, How can i modify this code to accept LLR's for coded symbols and produces LLR's for information and parity bits simultaneously. thanks alot.

Does this decoder perform better than the original viterbi decoder in terms of BER?
15 Feb 2010 Soft Input Soft Output Viterbi Algorithm Implementation of the SISO Viterbi algorithm. Author: Adrian Bohdanowicz Ammar

Hi. Any clues what kind of input codeword it expects. Real number, complex etc. I want encode and decode for the case of QPSK with a pi/4 phase shift.

Thanks in advance
