For these methods, the number of "iterations" (output with the

blockThe number of the block, from zero decodingA possible decoding for the message bits, expressed as a hexadecimal number. The other bits are determined by the message bits. likelihoodThe likelihood for this decoding (ie, the probability of obtaining the data received if this was the message sent).

The number of "iterations" (output with the

blockThe number of the block, from zero iterThe number of an iteration, zero for the initial state. changedThe number of bits in the decoding that differ from the bit that would be chosen based just on the likelihood ratio for that bit. Bits whose likelihood ratios are exactly one contribute 0.5 to this count. (Likelihood ratios of exactly one can arise when the output of an AWGN channel rounds to exactly 0.00.) perrsThe number of parity check errors in the current tentative decoding. loglikThe log likelihood of the current tentative decoding. EperrsThe expected number of parity check errors in a decoding found by randomly picking a value for each bit, independently, according to the current bit probabilities. EloglikThe expected log likelihood of a decoding found by randomly picking a value for each bit, independently, according to the current bit probabilities. entropyThe entropy (in bits) of the distribution defined by the current bit probablities, assumed to apply to bits independently.
