dc.description.abstract本篇論文中,我們提出一種將M-QAM正交分頻多工系統中的資料區塊分割為非互斥子區塊的改良型部分傳輸序列演算法。由於16-QAM星座圖可以由兩個QPSK及四個BPSK的集合構成,如此便可分別在兩個QPSK或四個BPSK區塊上使用不同的互斥分割,即整個16-QAM資料區塊等同於非互斥子區塊。模擬結果顯示,此種非互斥子區塊分割方式在使用插入分割、鄰接分割及隨機分割上PAPR性能皆優於傳統互斥分割的部份傳輸序列。此種非互斥子區塊演算法也可與其他降低複雜度的演算法做結合,進一步達到更好的效能。zh_TW
dc.description.abstractA modified PTS algorithm by partitioning an OFDM block into non-disjoint OFDM sub-blocks is presented in this paper for PAPR reduction of M-QAM OFDM signals. Since a 16-QAM constellation can be written as sum of two QPSK sets, respectively four BPSK sets, a non-disjoint sub-block partition of the 16-QAM OFDM block is obtained by applying two different disjoint partitions on QPSK OFDM blocks, respectively four different disjoint partitions on BPSK OFDM blocks. Compared to a disjoint sub-block partition in conventional PTS, numerical results show that themodified PTS with a non-disjoint partition achieves an improvement of PAPR reduction and BER performance for interleaved, adjacent, and random partitioning schemes.en_US
