摘　　要：目前虽然存在很多超宽带通信系统实现方案,但对这些方案的综合性能评价和应用场景分析方面的研究较少.本文介绍了超宽带技术的研究现状,分析了其潜在的应用场景,并给出了超宽带通信系统的实现方案模型.通过对超宽带通信系统中基带调制、抗多径处理、扩频和载波变频这四类技术的研究和应用场景分析,以通信速率、通信距离、实现复杂度和功耗为主要评价标准,给出了12种满足功率谱密度限制和6种不满足功率谱密度限制的典型超宽带通信系统实现方案的应用场景.这些研究对超宽带通信系统的优化设计和多元化发展具有重要意义.Although there are many implementation schemes for the ultra-wideband communication system now,there are not many researches done on the comprehensive performance evaluation and application scenario analysis.This paper describes the research status of the ultra-wideband technology,analyzes its potential application scenarios,and presents the implementation model for the ultra-wideband communication system.Based on the researches and application scenario analysis of baseband modulation,anti-multipath processing,spread spectrum and frequency carrier technologies in the ultra-wideband communication system,and taking the communication rate,communication distance,implementation complexity and power consumption as the main evaluation criteria,this paper provides the application scenarios of typical implementation schemes for the ultra-wideband communication system,including 12 kinds which meet the power spectrum density limit and 6 kinds which do not.The researches are significant in the optimized design and diversified development for the ultra-wideband communication system.
