碩士 === 國立中央大學 === 通訊工程研究所 === 92 === 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.
