Detecting redundant digital codewords using a variable criterion

摘要

Fast response detection of repeatedly transmitted redundant digital codewords is provided by checking the same bit-position in consecutive n bit codewords. The number m of codewords checked is increased until the number of equal bit values reaches a varying threshold jm dependent upon m, or until m reaches a maximum M. This sequence is repeated for each of the remaining bit-positions of the codeword. Faster response is provided when an early threshold is reached, eliminating the need to continue checking the same bit-position in the remainder of the M codewords.
