摘要: 
在本篇論文中,我們提出一新型演算法結合區塊碼籬笆結構與部分傳輸序列以降低正交分頻多工信號之峰均功率比。此一演算法使用一具有良好最小碼籬笆結構之區塊碼組成所有權重因子,選擇出具有最小峰均功率比之正交分頻多工信號並產生具有錯誤更正能力的額外訊息位元。結合籬笆結構與部分傳輸序列策略之目標為二:提供低複雜度之部分傳輸序列供權重因子之搜尋、增強額外訊息位元之錯誤保護能力。模擬結果顯示出與其他已提出之方法相比,此一方法在低複雜度下提供良好的峰均功率比降幅。

In this thesis, we present a novel algorithm for PAPR reduction of OFDM signals by combining the PTS technique in the minimal trellis of linear block codes. The proposed algorithm uses a given linear code, consisting of all possible weighting factors, with good minimal trellis to select the transmitted OFDM signal with minimum PAPR and to transmit the side information with error correction. The goals of this combining strategy of trellis and PTS are twofold: 1) to provide a low complexity PTS for weighting factor search and 2) to highlight the error protection capability for side information. Simulation results show that the proposed scheme achieves good PAPR reduction with lower complexity, compared to other PTS approaches.
