conversations.

That algorithm is applied to higher-rate Reed-Solomon codes on a symmetric
channel using binary phase-shift keying (BPSK).
Our 64-ary input channel with 64-FSK modulation required us to develop
unique methods for assigning erasure probabilities and for defining acceptance
criteria to select the best codeword from the list of tested candidates.
