An efficient synchronizer for OFDM-based UWB system was proposed

which consists of the filter-free symbol synchronizer

frequency synchronizer with improved Moose algorithm and sign-based auto-correlator. According to the results of synthesis using SMIC

0.13μm CMOS process

the proposed design can achieve the throughput requirement with only 24% gate count and 25% power consumption of the conventional four-parallelism approach.
