Summary:The method includes receiving a signal comprising a received frame, the received frame having a plurality of received symbols and having a received information portion and a received frame quality indicator; storing at least one of the plurality of received symbols in a memory; demodulating the received information portion to form a demodulated information portion and demodulating the received frame quality indicator to form a demodulated frame quality indicator, the demodulated information portion and the demodulated frame quality indicator comprising a demodulated frame; re-encoding at least a portion of the demodulated frame to form an encoded frame, the encoded frame having a plurality of encoded symbols; comparing one of the plurality of encoded symbols with the at least one of the plurality of received symbols stored in the memory; and based on the comparison, estimating the channel parameter.
