Patent ID: 8126074

Claim:
A baseband processor comprising: a channel estimator configured to generate an estimate of a channel for each sub-carrier of a frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol, and generate channel state information corresponding to each sub-carrier of the frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol; a demodulator configured to generate a plurality of demodulated symbols based, at least in part on, the estimate of the channel for each sub-carrier of the frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol, each demodulated symbol corresponding to a given sub-carrier of the frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol; and a Viterbi decoder configured to (i) perform a soft-decision decoding on each demodulated symbol and (ii) generate a corresponding soft-decision decoded symbol, wherein the soft-decision decoding of each demodulated symbol is based, at least in part, on the channel state information corresponding to the given sub-carrier associated with the demodulated symbol.
