本篇論文旨在探討超寬頻(Ultra-WideBand, UWB)通訊系統於多重接取環境下的效能,UWB系統目前正由美國聯邦通信委員會(Federal Communication Commission, FCC, [1])制定規範中。利用脈衝無線電(Impulse Radio)訊號是實現UWB系統的主要方式之一(也有使用弦波的訊號),也是本篇論文所採取的主要架構。多重接取通訊系統,必須有效區分不同的使用者所傳送的訊號,Impulse Radio主要以跳時碼(Time Hopping Code)來區分每個使用者之間的訊號,我們比較隨機整數(Random Integer, RI)碼、直接序列(Direct Sequence, DS)碼、光學正交碼(Optical Orthogonal Codes, OOC)以及有限投影平面(Finite Projective Plane, FPP)碼。經電腦模擬分析後,FPP碼比其他三種在單一使用者及多使用者的情況下,都擁有較好的特性表現。
This thesis primary intention is discussing the Ultra-WideBand communication system in multiple access environment performance, UWB system now is formulating in the standard by the Federal Communication Commission,[1]. Realizes one of UWB system fundamental modes using Impulse Radio signal, also is the main construction which this thesis adopts. Mainly differentiates between each user''''s signal by Time-Hopping code, we compare Random-Integer code, Direct-Sequence code, Optical Orthogonal code and Finite Projective Plane code. After computer simulation analysis, the FPP code has the better characteristic performance compared to other three kinds in the single user and multi-users'''' situation.
