摘要/Abstract

摘要： 针对改进的多带并发UWB通信系统的干扰检测算法和干扰抑制性能进行了分析.鉴于传统多带UWB调制方案的不足,对改进的多带并发UWB通信系统进行了数学分析和描述.在此基础上,提出了一种新的低采样率的共存干扰检测算法——并发子带干扰检测算法,并对该算法进行了数学分析和系统仿真.分析和仿真结果表明,该算法可在信号帧速率的采样量级上,完成对共存窄带干扰的有效检测,并与多带并发UWB系统的干扰抑制处理相结合,可对共存干扰进行有效抑制,明显改善共存UWB系统的误码率性能.

Abstract: The performance of interference suppression for parallel multi-band ultra-wideband communications is analyized.The new algorithm named parallel sub-pulse interference detection is proposed.This new algorithm can be realized in low level sample rate.Mathematics analysis and computer simulation for the new algorithm are made.The simulation results show that the new algorithm can detect the coexisting interference effectively in low smaple rate and improve the BER performance of the parallel multi-band UWB communication system evidently combined with interference suppression measures.
