Abstract
In this paper, a blind narrowband interference (NBI) mitigation technique using the combination of a square law (SL) device and a band pass filter (BPF) is proposed for energy detection (ED) based ultra-wideband (UWB) receivers. Both theoretical analysis and computer simulations show that without requiring any prior knowledge about the NBI, the SL technique can considerably improve signal-to-interference ratio of the received UWB pulses and hence allows ED-based UWB receivers achieve much better bit error rate. Furthermore, the proposed SL technique has the same NBI mitigation performance as the Teager-Kaiser operator (TKO) technique. Unlike TKO, there are many commercial off-the-shelf SL devices are available for IR-UWB applications. Thus, the proposed SL technique is a simple, implementable, and highly effective blind NBI mitigation technique for ED-based IR-UWB receivers. © 2012 IEEE.
