Abstract
A method includes generating representative noise variance estimates based on a plurality of received symbols received in an orthogonal frequency division multiplexing (OFDM) signal. The representative noise variance estimates correspond to respective frequency intervals of a plurality of frequency intervals of the OFDM channel. Individual frequency intervals of the plurality of frequency intervals include a plurality of contiguous frequency bins of the OFDM signal.
