Abstract

In this paper we present the Peak-to-Average Power Ratio decrease method targeted at energy efficiency improvement of the Radio-over-fiber telecommunication systems based on the Orthogonal Frequency Division Multiplexing. The scheme for the proposed method that consists in the signal precoding with discrete function is discussed in details. The simulation results obtained for five different precoding functions: Discrete Hartley Transform, Discrete Cosine Transform, Discrete Sine Transform, Fast Walsh-Hadamard Transform, and Discrete Fourier Transform, show the peak-to-average power ratio decrease of the transmitted signal up to 7 dB without degradation in noise immunity. Such a gain in transmitted power reduction corresponds to energy efficiency improvement by 5.15 dB in the case of 16-position quadrature amplitude modulation. The experimental study confirms the simulation results, providing the 6.5 dB peak-to-average power ratio decrease for Discrete Fourier Transform function.

采用减小PAPR方法提高基于ofdm的光纤无线通信系统的能效

本文提出了一种基于正交频分复用技术的峰值平均功率比降低方法，以提高光纤无线电通信系统的能效。详细讨论了离散函数信号预编码方法的实现方案。对离散Hartley变换、离散余弦变换、离散正弦变换、快速Walsh-Hadamard变换和离散傅立叶变换五种不同的预编码函数进行仿真，结果表明，传输信号的峰均功率比降低了7 dB，而噪声抗扰性没有下降。在16位正交调幅的情况下，这种传输功率降低的增益相当于能量效率提高了5.15 dB。实验研究证实了仿真结果，离散傅里叶变换函数的峰均功率比降低了6.5 dB。
