@devang agree, that we have to think about FEC. Viterbi is not the best FEC for OFDM. Because OFDM has a block nature -- block code seems like a better choice. I am big fan of LDPC. Soft-bit LDPC decoder on 60+ bit block size has BER/SNR properties very close to Shannon limit. Also if we aim to make OFDM symbol size configurable, we can generate reasonable LDPC code matching OFDM symbol size. I have another repo for LDPC project ;) https://github.com/drom/LDPC
