本論文將探討正交多工正交振幅調變(Orthogonally Multiplexed Orthogonal Amplitude Modulation : OMOAM)系統，由於頻率偏移所造成的子通道間相互干擾(Interchannel Interference : ICI)問題。首先，分別針對OMOAM系統提到的四種正交基底，建立其ICI問題的數學模型，並且以訊號干擾比(Signal to Interference Ratio:SIR)作為評估ICI問題的指標。然後再利用這些數學模型，逐一對個別的基底，觀察OMOAM系統的各個調變參數對SIR曲線的影響。最後將觀察結果做一個整理。 The interchannel interference (ICI) on account of frequency offset in the orthogonally-multiplexed orthogonal amplitude modulation (OMOAM) system is investigated in this thesis. In the first place, we establish the mathematical m- odel of the ICI problem individually for the four kinds of orthogonal basis set mentioned in OMOAM, and take the signal-to-interference-ratio (SIR) with re- spect to the frequency offset as an indicator while evaluating the ICI problem. Consequently we take advantage of the derived mathematical model to simula- te and observe how the SIR curve be affected by the modulation parameters in OMOAM. Eventually, we summarize the results observed by the simulation as our conclusion.
