ABSTRACT:
A receiver configured for: a) receiving (410) a first OFDM symbol and generating a plurality of demodulated symbols for the first OFDM symbol; b) generating (420) decoder output code symbols corresponding to a subset of the plurality of demodulated symbols; c) determining (430) that a set of the decoder output code symbols make up a set of reference symbols corresponding to at least a portion of the subset of the plurality of demodulated symbols; d) generating (440) the set of reference symbols; e) generating (450) a set of channel estimates based on the set of reference symbols and the at least a portion of the subset of the plurality of demodulated symbols, for use in decoding a current OFDM symbol; and f) repeating steps b-e until a channel estimate for each demodulated symbol corresponding to the first OFDM symbol has been generated.
