本論文主要是探討一新型的正交多工振幅調變信號[1]( Orthogonally-Multiplexed Orthogonal Amplitude Modulation,簡稱OMOAM )性能。在本報告中，我們探討同調偵測( Coherent detection ) 的正交振幅多工(OMOAM)接收機以最佳化解調[1]( Optimum Demodulation )與次佳化解調( Sub-optimum Demodulation )的性能。除了以數學分析的方法探究及比較接收方式的性能外，我們也以電腦模擬的方式驗證數學分析結果的正確性。最後我們探討在門檻值偏移時之次佳化解調的數學分析。 A novel class of coherent Orthogonally Multiplexed Orthogonal Amplitude Modulation [1](OMOAM) signals is investigated in this thesis. An exact analysis on the bit error probability is presented for a coherent OMOAM sub-optimum receiver, and verified by computer simulation. The performance comparison between the optimum [1] and sub-optimum OMOAM receivers are also illuminated. The performance of the sub-optimum coherent receiver in the presence of imperfect power estimation is also considered.
