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...
In this paper, a blind narrowband interference (NBI) mitigation approach using a filter bank (FB) is proposed for energy detection (ED) based UWB receiver. By comparing the received signal energy of the filter branches, the proposed FB-ED UWB receiver can achieve effective dynamic NBI detection and mitigation without requiring any transmission of preamble prior. Simulation results show that the proposed...
Impulse radio ultra-wideband (IR-UWB) receivers based on kurtosis detector (KD) can achieve much better performance than those based on energy detection (ED). However, when narrowband interferences (NBIs) are present, the KD-based receivers suffer serious performance degradation. In this paper, a modified KD (MKD) is proposed to improve the NBI mitigation ability of the UWB receiver. Computer simulation...
Presently most signal processing technologies employed in impulse radio UWB transceivers are straightforward derivatives of those designed for conventional wireless transceivers. They appear not to take full advantage of some special features offered by the impulse radio UWB transceivers, such as ultra-wide bandwidth and very short duration pulses. To move beyond this shortcoming, in this paper, we...
