Abstract
A delay lock loop algorithm is proposed, in which the correlation sequence is obtained from the received signal by analyzing the OFDM signal. The algorithm is a waveform-based timing tracking one, in which the OFDM signal is thought of as a whole. At the same time the algorithm has nothing to do with modulated information and the carrier frequency offset, and overcomes the impact of ICI. The simulator results show that the algorithm can work properly at low SNR.
