OFDM系统中一种新的分块迭代的部分传输序列算法

A Novel Block Iterative Algorithm of PTS in OFDM

该文提出了一种新的基于分块迭代(BI)和自适应分块迭代(ABI)的部分传输序列算法,能够有效地降低正交频分复用(OFDM)系统的峰均功率比(PAPR),与原始部分传输序列(OPTS)和Iterative Flipping(IF)算法相比,该算法能够获取更好的性能与复杂度的折衷,并且该算法可以看作OPTS和IF算法的一般化形式。

A novel Block Iterative （BI） and Adaptive Block Iterative （ABI） based schemes of Partial Transmit Sequence （PTS） for Peak to Average Power Ratio （PAPR） reduction in Orthogonal Frequency-Division Multiplexing （OFDM） are proposed, which can effectively reduce the high PAPR caused by OFDM. Compared with the Original Partial Transmit Sequence （OPTS） and Iterative Flipping （IF） algorithm, the proposed schemes can obtain much better tradeoff between performance and complexity, and can be considered as the generalization of OPTS and IF algorithm.
