摘要: 在本篇論文中,我們提出四種基於樹狀圖所架構之低複雜度部分傳輸序列演算法用以降低正交分頻多工系統的峰均功率比值。 這些被提出的演算法藉由搜尋不同線性區塊碼的樹狀圖來得到所有的相位因子,接著選擇一組具有最小峰均功率比值之正交分頻多工訊號來傳輸並且產生具有錯誤更正能力的訊息位元。 比較傳統的部分傳輸序列和我們的演算法,你將會明白用我們的演算法搜尋相位因子,則運算複雜度是比較低的。 因此,在我們的演算法中有兩個主要的優點,即降低搜索的複雜度和訊息位元提供額外的錯誤更正能力。
In this paper, we propose four low complexity partial transmitted sequences (PTS) algorithms that are based on the tree diagram for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. The prorpsed algorithms can obtain all phase factors by searching the tree diagram of different $(n,k)$ linear block codes, and then select an OFDM signal with minimum PAPR for transmitting and transmit the side information with error correction. Compare conventional PTS (C-PTS) with our algorithms, you will know our algorithms which are low computational complexity for searching phase factors. Therefore, there are two main advantages in our algorithms , i.e. lower searching complexity and the side information provides extra error-correction property.
