you used the values of MAP decoder directly for the BER plot. Which MAP decoder you used for this simulation ? If possible can you share the code

Is this BCJR decoding?

[SebastianCa]

As the codes are extremely short (<16 bits) we can simply implement a brute-force MAP decoder by checking all possible codeword candidates.

For example if k=8 we have 2^8=256 codeword candidates that need to be checked and the decoder selects the one with the smallest distance. This works for Polar and for the random code.

@SebastianCa , can you please share the code you used for the MAP decoder (or include BER for bigger values of SNR)?

I may need that too, please
