The Effects of Narrowband Interference on Finite-Resolution IR-UWB Digital Receiver

TL;DR

This paper investigates how narrowband interference affects finite-resolution IR-UWB digital receivers, revealing that lower resolution amplifies interference impact and degrades system performance.

Contribution

It provides the first detailed analysis of NBI effects on finite-resolution IR-UWB receivers, highlighting the resolution-dependent degradation.

Findings

Finite-resolution receivers are more susceptible to NBI.

Lower resolution leads to greater performance degradation.

NBI impact increases as receiver resolution decreases.

Abstract

Finite-resolution digital receiver is recently considered as a potential way to Ultra Wide Band (UWB) communication systems due to its ability of mitigating the challenge of Analog-Digital Converter (ADC). In this paper, the effects of narrowband interference (NBI) are investigated when finite-resolution digital receiver is used for Impulse Radio-UWB (IR-UWB) system. It is shown that finite-resolution receiver enlarges the impact of NBI. The lower resolution of the UWB receiver is, the more degradations NBI causes.
