Abstract

To address the issue of interference caused by power line channel noise on time transmission signals, a power line time transmission technology based on OFDM modulation is proposed to use linear frequency modulation (LFM) and direct sequence spread spectrum (DS) techniques for its subcarriers. The simulation results show that the power line time transfer technology using LFM-OFDM and DS-OFDM modulation can effectively reduce the bit error rate of the received signal. At the same time, compared to DS-OFDM modulation technology, the power line time transfer technology using LFMOFDM modulation has a lower bit error rate of the received signal.
