摘要(中)

本論文擬對一新型調變家族─正交多工正交振幅調變[1] ( Orthogonally-Multiplexed Orthogonal Amplitude Modulation ) ，探討其非線性放大狀況下的互調變效應。論文中，使用放大器的三次諧波參數(Third-Order Harmonic)來設定非線性模型，而訊號的互調變效應(Intermodulation Effect)以頻帶內的功率來衡量，探討了第二類基底和第四類基底，在不同調變參數下，互調變的功率與趨勢。此外，並對傳輸率(Transmission Rate)與頻譜效益(Spectral Efficiency)加以考量，來作一綜合性的評估。

摘要(英)

A novel class of coherent Orthogonally-Multiplexed Orthogonal Amplitude Modulation (OMOAM) [1] signal is investigated in this thesis. The research focuses on the intermodulation effect caused by the nonlinear characteristic of the amplifiers such as high power amplifiers and solid-state power amplifiers. Intermodulation power is derived by an exact analysis, and the trends of the transmission rate and spectral efficiency are including to be compared.
