Abstract:
1. An apparatus, comprising: an LDPC (Low Density Parity Check) encoder to encode a plurality of bits to generate at least one LDPC codeword; a sub-carrier interleaver module, coupled to the LDPC encoder, to assign bits of the at least one LDPC codeword to a plurality of sub-carriers within an orthogonal frequency division multiplexing (OFDM) spectrum to generate a plurality of bit labels such that each of the plurality of bit labels corresponds to one of the plurality of sub-carriers and adjacent bits of the at least one LDPC codeword are maximally separated among the plurality of sub-carriers within the OFDM spectrum; a symbol mapper module, coupled to the sub-carrier interleaver module, to map the plurality of bit labels to a plurality of modulations to generate a plurality of modulation symbols; and a modulator to process the plurality of modulation symbols to generate a continuous time signal that is launched into a communication channel.
