    Abstract: 在本篇論文中將探討一新型的調變家族正交多工正交振幅調變 (Orthogonally-Multiplexed Orthogonal Amplitude Modulation, OMOAM)的 訊號之峰均功率比趨勢 (peak-to-mean envelope power ratio, PMEPR) 。 首先,基於正交多工正交振幅調變模型分析它的訊號之峰均功率比 趨勢,並提供一些一般性的觀察結果。接著,指定一些特定的基底 做為正交多工正交振幅調變的基底集合,逐一地分析它們的訊號之 峰均功率比趨勢,並列表整理之。最後我們藉由這些分析結果,做 更進一步的觀察,提供一些有用的觀察結果及使用上的建議。 A new study for coherent orthogonally-multiplexed orthogonally amplitude-modulated (OMOAM) signals is investigated in this project. We present the PMEPR trends and its boundaries in analysis for the OMOAM model based on different basis sets. At first, we find the PMEPR does not diverge with parameter K. Otherwise, the OMOAM can trade lower bit rate in lower PMEPR within fixed parameters-product ML. In addition, the upper bounds of PMEPR have one common factor . Finally, according the results, we proposed the methods that can make PMEPR lower for using OMOAM signals.
