    Abstract: 在本篇論文中將討論使用選擇性映射於正交多工調變系統中的峰均功率比效能,在第二章將說明正交多工正交振幅調變和正交多工正交相位調變,及其使用快速傅立葉轉換來實現,而解調是使用次佳化解調。在第三章將說明使用選擇性映射中,相位的選取以及相位序列的產生方法。接著,後面的章節中,將說明使用選擇性映射於正交多工調變系統的模型和其系統參數對於峰均功率比的影響及趨勢。在第四章將說明選擇性映射之附帶訊息,接著,在正交多工系統中使用選擇性映射並觀察其附帶訊息對於系統錯誤率效能的影響。在第五章 中,將對於本篇論文作結論。 Selective mapping (SLM) peak-power reduction is distortionless as it selects the actual transmit signal from a set of alternative signals, which all represent the same information. The specific signal generation information, called side information, needs to be transmitted and carefully protected against bit errors. Here, we employ SLM in OMOAM (Orthogonal Multiplexing Orthogonal Amplitude Modulation) and OMOPM (Orthogonal Multiplexing Orthogonal Phase Modulation). Beside, we also discuss the complexity which is produced by SLM in the system, and observe the influence of PAPR(Peak to Average Power Ratio) due to the change of system parameters. Even though SLM is applicable with any modulation, we concentrate on orthogonal multiplexing orthogonal in this thesis.
