降低OFDM系统峰均功率比的低计算复杂度PTS方法
摘要
针对传统PTS方法计算复杂度大的缺点
提出了一种新的低计算复杂度PTS(LCC-PTS)方法。该方法利用相位加权序列之间的关系
简化了产生部分候选序列的运算过程
从而达到降低计算复杂度的目的。性能分析结果表明
与传统PTS方法相比
LCC-PTS方法在大大降低计算复杂度的同时
系统的PAPR性能完全没有损失。
Abstract
Concerning that the main drawback of conventional PTS was the large computational complexity
a new low computational complexity PTS (LCC-PTS) scheme was proposed. In LCC-PTS
the computation for candidate signals was simplified by making use of the relation between phase weighting sequences
which resulted in reducing computational complexity dramatically. Performance analysis show that
compared with conventional PTS
the proposed LCC-PTS scheme can be implemented with lower computational complexity while at no loss of PAPR(peak-to-average power radio) performance of the system.
