The SFRSD algorithm uses information available from the demodulator to assign
a variable probability of erasure to each received symbol.
The erasure probability for a symbol is determined using two quality indices
that are derived from the the JT65 64-FSK demodulator.
The noncoherent 64-FSK demodulator identifies the most likely received
symbol based on which of 64 frequency bins contains the the largest signal
plus noise power.
