Abstract
A communication method and device which can improve error correction performance and power consumption without increasing hardware complexity is disclosed. A communication apparatus includes: a decoder for polar codes, that decodes a codeword in which a frame is partitioned according to a predetermined partitioning rule and each partition includes at least one check bit computed by a predefined checksum equation; a memory that stores a frozen set including frozen bit indices, a non-frozen set including non-frozen bit indices, and a susceptible to error (STE) set including STE indices susceptible to decoding error for each partition; and a controller configured to: compute a check sum of at least one decoded bit for each partition according to the predefined checksum equation; responsive to failure of checksum, initiate a recurrent decoding attempt on the partition; and perform a bit-inversion operation on at least one STE index in each recurrent decoding attempt.
