Abstract

In this paper, a multichannel energy detection (MED) receiver based on nonlinear square law (SL) technology is proposed for ultra-wideband (UWB) system. By using a group of band-pass filters, the received signal processed by SL device is separated into multiple channels, and then the channel with serious narrow band interference (NBI) will be omitted to improve the NBI mitigation ability of the receiver. Simulation results show that comparing with conventional ED receivers, the proposed SL-MED receiver can significantly improve the bit-error-rate performance when one or two NBIs are present and even no NBI presents.
