Abstract:
1. An apparatus comprising: an input configured to receive an orthogonal frequency division multiplexing (OFDM) signal that includes a plurality of data tones and a plurality of pilot tones from a communication channel; a slicer configured to generate a plurality of data tone hard decisions and a plurality of data tone error terms based on the plurality of data tones and to generate a plurality of pilot tone hard decisions and a plurality of pilot tone error terms based on the plurality of pilot tones; and a channel estimator configured to generate a channel estimate of the communication channel based on the plurality of pilot tone hard decisions, at least one of the plurality of pilot tone error terms, and at least one of the plurality of data tone error terms; and wherein: based on a channel estimate of the communication channel, the slicer is configured to generate at least one additional plurality of data tone hard decisions based on the plurality of data tones.
