A method and apparatus for receiving an analog radio frequency signal comprising a time-domain analog OFDM symbol. The method includes converting the time-domain analog OFDM symbol into a corresponding time domain digital OFDM symbol; converting the time domain digital OFDM symbol into a frequency domain digital OFDM symbol; generating an estimate of the channel for each sub-carrier of the frequency domain digital OFDM symbol; demodulating the frequency domain digital OFDM symbol and generating 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 OFDM symbol; and performing a soft-decision decoding on each demodulated symbol and generating a corresponding soft-decision decoded symbol, wherein the soft-decision decoding of each demodulated symbol is based, at least in part, on the estimate of the channel corresponding to the given sub-carrier associated with the demodulated symbol.
