Hello. I have a problem with uplink GSM burst processing because of unknown freq offset. With all other GSM receiving steps implemented(time sync, channel estimation, mlse equalizer) there is strong BER increasing due to frequency offset. Realization is in fixed-point machine so I try to avoid division and atan operation for carrier estimation. Who can give me some info about feedback methods or correlation based method (with multipath channel presents) for carrier frea recovery. I have one sample per symbol baseband GSM signal. Thanks. Pavel Schukin.
