1. A current channel realization decoding method, the method comprising:
at a receiver, receiving a signal from a propagation channel, the signal comprising a received vector, the received vector having n bits;
selecting k bits from the n bits, the k bits being the most reliable k bits of the n bits according to a reliability metric;
ordering the k bits to obtain first ordered k bits, according to current channel realized reliability metrics for the k bits;
identifying most reliable independent bits in the k bits;
generating a set of bit-flip patterns by sorting the identified most reliable independent bits to obtain second ordered k bits, and using the second ordered k bits to generate bit-flip patterns;
identifying ones of the bit-flip patterns in the set with current channel realized reliability metrics below a maximum reliability metric threshold;
creating a bit flip schedule to order the identified ones of the bit flip patterns of the set, each bit flip pattern comprising one or more of the selected k bits, using the current channel realized reliability metrics for the k bits, wherein unidentified ones of the bit flip patterns are excluded from the bit flip schedule; and
attempting to decode the received vector by performing bit flip attempts according to the bit flip schedule.
