摘要: 
在此論文中,我們提出兩個新種跳時超寬帶( UWB )系統,稱為“M-元跳
時脈衝位置調變與隨機極性超寬頻系統”,另一個系統被稱為“多脈衝跳時M-
元跳時脈衝位置調變與隨機極性超寬頻系統”。基於特徵函數分析( CF )的技
術,我們得出多重路徑干擾的機率分佈,平均符號間錯誤率. M-元跳時脈衝位置
調變與隨機極性超寬頻系統和多脈衝跳時M-元跳時脈衝位置調變與隨機極性超
寬頻系統的模擬和分析是在有多個使用者干擾的白色高斯雜訊通道中進行。我們
將證明,M-元跳時脈衝位置調變與隨機極性超寬頻系統和多脈衝跳時M-元跳時
脈衝位置調變與隨機極性超寬頻系統優於傳統隨機隨機超寬頻系統。

In this thesis, we propose two new kinds of time-hopping (TH) ultra-wideband
(UWB) systems, called " Time-hopping M-ary PPM UWB with polarity
randomization system", and another system called "Multiple pulses time-hopping
M-ary PPM UWB with polarity randomization system". Based on the analytical
characteristic function (CF) technique, we also derive the probability distribution of
the multiple access interference (MAI) and the average probability of symbol
error.The simulation results of Time-hopping M-ary PPM UWB with polarity
randomization and Multiple pulses time-hopping M-ary PPM UWB with polarity
randomization systems are provided to verify the analytical frameworks in the
additive white Gaussian noise (AWGN) channel. We will shown that TH-MPPM
UWB with polarity randomization and MP-TH-MPPM UWB with polarity
randomization systems outperform the conventional one and without polarity
randomization UWB systems.
Keywords : ultra-wideband (UWB), time-hopping (TH), multiple access
