Abstract

In this paper, we propose a new approach to minimize the Peak-to-Average Power Ratio (PAPR) which is considered as the main obstacle at the receiving end through the Orthogonal Frequency Division Multiplexing-based Power Line Communication (OFDM-PLC) channel. The proposed method is based on the combination of a modified selective mapping (MSLM) and a modified Partial transmit sequence (MPTS) with a novel clipping function (NCF) to design two new techniques namely, MSLM-NCF and MPTS-NCF, respectively. In this context, the MSLM introduces a novel phase factor depending on the diagonal coefficients of Riemann matrix while the MPTS uses a suboptimal combination algorithm that can effectively reduce the time complexity. In addition, the NCF process uses a novel strategy to clip the impulsive bursts. Consequently, the proposed techniques can efficiently mitigate both the impulsive noise (IN) and the PAPR generated over the OFDM-PLC channels. Performance evaluation of the proposed techniques is measured in terms of BER (bit error rate), MSE (mean square error), and CCDF (complementary cumulative distribution function) by using a well known PLC channel model. Obtained results are shown to be superior to the often referenced well-known methods in the literature.

基于ofdm的电力线通信中提高PAPR和脉冲噪声抑制性能

在本文中，我们提出了一种新的方法，通过基于正交频分复用的电力线通信（OFDM-PLC）信道，将峰值平均功率比（PAPR）最小化，这被认为是接收端的主要障碍。该方法将改进的选择性映射（MSLM）和改进的部分传输序列（MPTS）与新颖的裁剪函数（NCF）相结合，设计了MSLM-NCF和MPTS-NCF两种新技术。在这种情况下，MSLM引入了一种新的依赖于黎曼矩阵对角系数的相位因子，而MPTS采用了一种次优组合算法，可以有效地降低时间复杂度。此外，NCF过程采用了一种新颖的策略来剪切脉冲爆发。因此，所提出的技术可以有效地减轻OFDM-PLC信道上产生的脉冲噪声（IN）和PAPR。通过使用众所周知的PLC信道模型，根据误码率（BER）、均方误差（MSE）和互补累积分布函数（CCDF）对所提出的技术进行性能评估。所得结果优于文献中常用的已知方法。
