Patent ID: 8130853

Claim:
A receiver 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; 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 decoder including a metric calculator configured to calculate a decision metric for each sub-carrier of the frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol based, at least in part, on (i) the channel estimate corresponding to the sub-carrier and (ii) the demodulated symbol corresponding to the sub-carrier, and a Maximum Likelihood Sequence Estimation unit configured to estimate a most likely transmitted symbol for each sub-carrier of the frequency domain digital Orthogonal Frequency Division Multiplexing (OFDM) symbol based on the decision metric corresponding to the sub-carrier.
