| Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 106 === There are advantage in Orthogonal Frequency Division Multiplexing (OFDM), but there are no shortcomings. The most serious drawback is the excessive peak-to-average power ratio. The power generated when the sub-carriers are superposed causes the peak-to-average power ratio to be too high.Errors when passing through nonlinear amplifiers.In this thesis, we propose a method that is different from the disjoint Partial Transmit Sequence (PTS) to reduce the peak-to-peak average power ratio generated by an Orthogonal Frequency Division Multiplexing. We use the MPTS with the linear block to reduce the peak-to-average power ratio. Compared with the conventional PTS, this method not only has a lower peak-to-average power ratio, but also has lower computational.
