基于BPSK的低压电力线载波通信系统研究
Research on BPSK-based carrier communication system of low-voltage power line
摘要
Abstract
The power line communication(PLC)technology is a communication mode to transmit the data or signal by means of power line. Since the low-voltage power line communication may suffer from the influence of the noise generated in the process of start/stop,switching and load variation of electric equipment,the noise source variety,noise spectrum characteristic and noise model of the low-voltage power line communication are analyzed in detail. A low-voltage power line communication sys-tem taking 240 kHz sinusoidal signal as the carrier wave is constructed. The band-pass filter based on Kasier window function is designed. The binary phase shift keying(BPSK)demodulation algorithm and its receiving performance are analyzed. The simula-tion and actual measured results show that the bit error rate of the designed BPSK modem is about 0.3% when the signal-to-noise ratio is -15 dB.关键词
