Orthogonal Hermite-Based Pulse Shapes Used for Ultra-Wide-Band Multi-user Communication
-
摘要: 正交Hermite脈沖被提出用于超寬帶無線通信。該文提出新方法用于超寬帶通信的多用戶傳輸系統(tǒng)。通過同時傳輸多個正交Hermie脈沖，超寬帶多用戶傳輸系統(tǒng)可以獲得好的性能特征。該文還提出了正交Hermite脈沖應用于UWB的DS-CDMA系統(tǒng)以同時支持更多的用戶通信。Abstract: 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.
