This paper proposes a joint frequency offset and delay profile estimation technique for TDMA mobile radio communications. In the proposed algorithm, the carrier frequency offset between transmission and reception is tracked from burst to burst, while the delay profile is estimated at the beginning of each burst. In each burst, estimated frequency offset is updated during delay profile estimation using the residual error of delay profile estimation. This technique is combined with an adaptive maximum-likelihood sequence estimation receiver for time varying multipath channels. Computer simulations have been performed to demonstrate the performance of the proposed algorithm. It is shown that the allowable frequency offset range of the proposed receiver is over 10 times as large as that of the conventional receiver without frequency offset compensation
