An area and power efficient frame synchronizer for 480Mb/s OFDM-based UWB system

Abstract

A novel frame synchronizer is proposed for OFDM-based UWB system. Integrating the improved matched filters and dynamic threshold design, the proposed design can reduce 65% area and 58% power with an acceptable performance loss. It can achieve 528MS/s throughput for 480Mb/s UWB system in 0.18 mu m CMOS process.
