摘要: 本篇論文中,我們提出一種將二位元里得-米勒碼與最小籬笆結構作結合的改良型部分傳輸序列技術來降低正交分頻多工系統中的峰均值功率比。我們將一組里得-米勒碼拆解成兩個子碼去作直和分解:錯誤更正子碼用來作消息位元,擾亂子碼用來作峰均值功率比的控制位元。我們使用低複雜度的最小籬笆結構,來找到一組具有最小峰均值功率比的擾亂向量。此方法不僅具有錯誤更正的能力且不用傳送額外訊息。
In this thesis, we present a modified PTS method which combines binary Reed-Muller (RM) codes with minimal trellis to reduce PAPR in OFDM systems. We decompose a RM code as a direct sum of an error correcting subcode for information bits and a scrambling subcode for PAPR control bits. The proposed algorithm employs a low complexity minimal trellis on the scrambling subcode to find a good scrambling vector with low PAPR. This method provided error correction capability without side information.
