摘要

本文在hotor和Tomlinson提出的延迟跳变传输参考(TR)超宽带通信系统窄带干扰(NBI)存在的情况下，提出了一种检测方案。我们推导了一个考虑了NBI和噪声影响的芯片级数据模型。该模型的有效性得到了验证，使用最小二乘检测算法实现了卓越的性能。仿真结果是在UWB传输与IEEE802.11a WLAN业务共存的实际场景下进行的

Detection of Delay-Hopped Transmitted-Reference UWB Signals Under Narrowband Interference

This paper presents a detection scheme for delay-hopped transmitted reference (TR) UWB communication systems, as the original TR technique proposed by Hoctor and Tomlinson, in the presence of narrowband interference (NBI). We derive a chip level data model which takes into account the effects of NBI and noise. The validity of the model is shown, enabling superior performance by using least squares detection algorithms. Simulation results are conducted under a practical scenario where the UWB transmission coexists with an IEEE802.11a WLAN service
