在正交分頻多工系統(Orthogonal Frequency Division Multiplexing , OFDM)有優點,但也有缺點,最嚴重的缺點是過高的峰均功率比值(Peak To Average Power , PAPR),在子載波疊加時所產生的功率會疊加造成瞬間的峰均功率比值過高,在通過非線性放大器時會產生錯誤。在本篇論文中,我們提出一種有別於互斥分割的部分傳輸序列(Partial Transmit Sequence ,PTS)的方法去降低正交分頻多工系統所產生的過高峰均功率比值。我們利用非互斥相交的部分傳輸序列搭配碼樹狀結構的線性區塊來降低峰均功率比值,與傳統的部分傳輸序列相較下,此方法不但擁有較低的峰均功率比值,還有較低的運算複雜度。

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.
