Claim 22:
23. The apparatus according to claim 22, the receiver further including:
a burst demultiplexer having an input coupled to the first output of the de-spreader and having an output;
a fine frequency corrector having an input coupled to the output of the burst demultiplexer and having an output;
a phase corrector having an input coupled to the output of the fine frequency corrector and having an output, wherein a plurality of pilots embedded in the received burst are used as matched filters to ensure proper timing of a payload due to potential sample slips associated with clock drifts;
a demodulator having an input configured to receive a plurality of symbols from the output of the phase corrector and having an output, said demodulator configured to demodulate the plurality of symbols, wherein the demodulator outputs a plurality of soft decision bits;
an error correction decoder having an input coupled to the output of the demodulator, having an output, and error correcting the plurality of soft decision bits using a predetermined forward error correction code, wherein said error correction decoder comprises a turbo decoder; and
a cyclic redundancy check decoder having an input coupled to the output of the error correction decoder, said cyclic redundancy check decoder configured to verify a plurality of error corrected data bits for errors before outputting a plurality of data bits.
