摘要

无线宽带业务严重依赖于正交频分复用(OFDM)技术。OFDM具有许多优点，适合于高速数据通信。OFDM的主要缺点之一是其高峰值平均功率比(PAPR)。有几种方法可以克服这个缺点。部分传输序列(PTS)就是其中之一。本文提出了迭代翻转算法的改进版本，即改进翻转PTS (M-PTS)，它缩小了迭代翻转算法(I-PTS)与传统PTS技术之间的性能差距。在提出的算法中，考虑了性能和复杂度的权衡，进行了性能分析。

On the performance analysis of Partial Transmit Sequence using modified flipping algorithm for PAPR reduction in OFDM systems

Wireless Broadband services heavily rely on Orthogonal Frequency Division Multiplexing (OFDM) technique. OFDM has several advantages which makes it suitable for high speed data communications. One of the major drawback of OFDM is its high peak-to-average power ratio (PAPR). There are several methods to overcome this drawback. Partial Transmit Sequence (PTS) is one of them. In this paper, a modified version of the iterative flipping algorithm has been proposed i.e. modified flipping PTS (M-PTS), which reduces the performance gap between the iterative flipping algorithm (I-PTS) and the conventional PTS technique. In the proposed algorithm, performance analysis has been done with considering performance/ complexity trade-off.
