| dc.description.abstract | 本論文擬對一新型調變家族─分別為正交多工正交振幅調變(Orthogonally-Multiplexed Orthogonal Amplitude Modulation)和正交多工正交相位調變(Orthogonally-Multiplexed Orthogonal Phase Modulation)，由於這兩種正交多工調變的峰均功率比(PAPR, Peak to Average Power Ratio)比較高，所以當訊號通過非線性放大器時，會產生非線性放大失真的問題。為了降低這個問題，我們在系統中使用了重複偵測方式(Iterative Detection)，來降低正交多工調變家族的非線性放大失真的影響，並且觀察在不同的調變參數下，非線性放大失真的趨勢與效能改善的情形。此外，並對3個不同的非線性放大器的失真
作效能比較，以及觀察重複偵測方式對非線性放大失真改善的情形。 | zh_TW |
| dc.description.abstract | Orthogonally multiplexed modulation (OMM) signals are investigated in this thesis. The research is focused on the application of the iterative detection of nonlinearly distorted OMM signals. In this thesis, we employ the iterative detection method to reduce the nonlinear distortion in orthogonal multiplexing orthogonal amplitude modulation (OMOAM) and orthogonal multiplexing orthogonal phase modulation (OMOPM). Three nonlinear distortion models are employed, and the results show that the performance trend of OMM distorted by these three models using the
iterative detection are the same. | en_US |
