A new transmission system using the Protective Earth conductor for Narrow-Band PLC

Abstract

One of the serious problems in the conventional transmission system, which uses the Neutral and Live (N-L) conductors, for the Narrow-Band Power-Line Communications (NB-PLC) is the low Signal to Noise Ratio (SNR) property. To improve it, a new signal transmission system, which uses the Protective Earth (N-PE) conductor instead of L, has been proposed in this letter. The proposed method is called N-PE system. The results show that the receiving SNR, the channel capacity, and the Packet Reception success Rate (PRR) values of the N-PE system were superior to those of the N-L system, except for the noise property.
