摘要
正交Hermite脉冲被提出用于超宽带无线通信。该文提出新方法用于超宽带通信的多用户传输系统。通过同时传输多个正交Hlermie脉冲,超宽带多用户传输系统可以获得好的性能特征。该文还提出了正交Hermite脉冲应用于LIWB的DS.CDMA系统以同时支持更多的用户通信。
Orthogonal Hermite pulse shapes used for Ultra Wide-Band(UWB) communication are proposed. The paper presents a novel method for multi-user transmission system in UWB communication. By transmitting multiple orthogonal Hermite pulses simultaneously, the UWB multi-user transmission system achieves good performance characteristic. Also it proposes that orthogonal Hermite pulses can be applied to the DS-CDMA system in UWB to access more users at one time.
