提出了一种降低OFDM系统峰均功率比的非均匀部分发送序列（NPTS）方法。基于导频辅助的压缩感知（CS）的信道估计已经与所提出的PAPR降低方法联合使用，以避免发送任何边信息。诸如正交匹配追踪的CS恢复算法用于信道抽头的估计。仿真结果表明，该方法降低了OFDM系统的峰均比，并具有准确的信道估计。
In this paper, nonuniform partial transmit sequences (NPTS) method has been proposed, for peak to average power ratio (PAPR) reduction in OFDM systems. Pilot assisted compressed sensing (CS) based channel estimation has been utilized jointly with the proposed PAPR reduction method to avoid sending any side information. CS recovery algorithms such as orthogonal matching pursuit are used for estimation of the channel taps. Simulation results demonstrate that the proposed technique decreases the PAPR of OFDM systems and has accurate channel estimation.
