摘要

高峰均功率比(PAPR)是带线性放大器的OFDM发射机的缺点之一。然而，许多现有的PAPR降低算法降低了频谱效率，但并没有带来任何显著的功耗降低。这个问题可以通过利用作为脉冲序列产生信号的发射机来解决。在本文中，我们描述了一种通过将原始OFDM信号转换成矩形载波上的信号来产生脉冲信号的方法。实验结果表明，所构建的脉冲OFDM信号可以被传统的OFDM接收机接收。

On the generation of Pulse OFDM signals

High peak-to-average power ratio (PAPR) is one of the disadvantages of OFDM transmitters with linear amplifiers. However, many of the existing PAPR reduction algorithms decrease spectral efficiency but do not bring any significant reduction in power consumption. This problem can be solved by the utilization of transmitters that are generating a signal as a sequence of pulses. In this paper, we describe a method for generating the pulse signal by converting the original OFDM signal into a signal on a rectangular carrier. It is demonstrated that the constructed Pulse OFDM signal can be received with a conventional OFDM receiver.
