Hello List, I've just merged some fine work by Bill, VK5DSP that has shown us how to generate LLRs for 4FSK, in order to use LDPC codes with 4FSK. Bill has summarised the Octave simulations he has developed in the GitHub PR:
https://github.com/drowe67/codec2/pull/129#issuecomment-653557681 At the top of the PR is a "Further Work" list. I would welcome new PRs from anyone who would like to push these changes through to the C version of the FSK modem.
