pub fn decode(llrs: &[i16], output: &mut [u8]) -> Result<usize, ConvError>Expand description
Decodes a convolutionally coded frame using soft-decision Viterbi.
llrs contains paired (G1, G2) log-likelihood ratios per trellis
step. Positive LLR means bit 0 is more likely. The trellis must
be terminated (K−1 tail steps appended by the encoder).
Returns the number of decoded data bytes written to output.
