| 摘 要： | 并行组合扩频通信技术( PCSS)和超宽带(UWB)通信技术因为具有高效通信能力和保密通信性能而成为该领域的研究热点.该文在分析并行组合扩频通信和超宽带通信系统技术特征的基础之上,结合这2种通信方式的技术优势,提出了一种基于并行组合扩频的超宽带通信系统方案,并将高性能的多元双正交键控(MBOK)调制方式应用到该系统.仿真结果表明,在相同条件下,当误码率为10-4时,MBOK调制方式较传统的脉冲位置调制(PPM)方式的信噪比有约9 dB的提高.

| Abstract: | Parallel combinatory spread spectrum(PCSS)and ultra wide band(UWB)technologies have efficiency and security capacity,so they become the hot spots of the research.This paper presents a new UWB communication system based on parallel combinatory spread spectrum after analyzing the characteristics of UWB and PCSS.The application of M-ary bi-orthogonal keying(MBOK)modulation in the new system is also discussed.The simulation shows that Eb/No is improved 9 dB in the system with MBOK modulation than the one in the... |
