A 528MS/s frequency synchronizer for OFDM-based UWB system

Abstract

A novel frequency synchronizer is proposed for 528MHz OFDM-based UWB system. It can reduce 75% memory and 59% power consumption through a low-power scheme based on data. partition. Measured result shows the proposed design can achieve 528MSamples/s throughput in 0.18 mu m CMOS process.
