Abstract:
1. A method for processing FEC frame header data, comprising: demodulating a received complex data symbol; computing an estimated pseudo-noise sequence using the demodulated complex data symbol; computing a binary correlation of the estimated pseudo-noise sequence with a Reed-Muller codeword; comparing the binary correlation with a first threshold to determine if a next received complex data symbol should be demodulated; decoding an estimated Reed-Muller codeword from said demodulated complex data symbol if said binary correlation is equal or greater than the first threshold; performing majority logic decoding on the estimated Reed-Muller codeword; computing a Reed-Muller symmetry measure on said estimated Reed-Muller codeword; comparing said symmetry measure with a second threshold to determine if a next received complex data symbol should be demodulated; and performing majority logic decoding to produce frame header data if said symmetry measure is greater than or equal to the second threshold.
