  • This paper presents a Polarity comparing and uniqueness guarantee (PCUG) timing synchronization estimation approach for MB-OFDM based UWB systems. Difference of the two cross correlation functions is computed, between a received symbol, the successive received symbol and predefined preamble sequence. It makes sense to propose polarity comparison and identification ideas to the scenario, for the result of cross correlation difference exceeding threshold is not always unique. If the polarity of the first exceeding threshold sample is different with that of predefined sequence, the current received sample is estimated to be the right timing point; otherwise the algorithm is put forward to find out a peak of correlation summation to figure out timing point. The proposed algorithm could make the uniqueness of timing index for sure. MSEs of PCUG are evidently lower than the reference algorithm. The total and exact synchronization probability could get as much as 98.98% and 95.92%.
