摘要
通信的高效性和安全性是衡量现代通信系统性能的2个主要技术指标,并行组合扩频通信技术和超宽带通信技术因分别具有高效通信能力和保密通信性能而成为该领域的2个研究热点.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上,结合这2种通信方式的技术优势,提出一种新的无线通信方案,并在新的通信系统中使用多进制脉冲位置超宽带调制方式,使该通信方案同时具有高效和安全的通信性能.仿真结果表明,并行组合扩频通信与超宽带通信具有结合的可行性以及MPPM是一种适合应用于并行组合扩频超宽带通信系统中的调制方式.
The efficiency and security of communication are the two main indicators for evaluating modern communication system performance.Parallel combinatory spread spectrum（PCSS） technology and ultra-wideband（UWB） communication technology are the two focuses of this field,because they have efficient communication capability and confidential communication performance respectively.On the basis of analyzing the features of PCSS and UWB communication technologies,by combining the advantages of these two ways,the authors put forward a new wireless communication program,which put the multiple pulse position modulation（MPPM） and UWB communication technologies into PCSS,so as to make the new program become efficient and secure.The simulation result shows that it is feasible to combine PCSS and UWB,and MPPM is a modulation way suitable for the new communication system.
