Simulation Study Low Voltage Power Line Carrier Communication in Noisy Environments

Studies have shown that there are a lot of low-voltage power line is one of the main obstacles to strong noise limit for data transmission quality. Power line noise can be divided into steady background noise, narrowband interference noise, sudden impulse noise and periodic noise. Background noise is distributed throughout the communication band, low-voltage power line up white Gaussian noise 22dB [133 or more. Sudden noise is generated by the random access or disconnect electrical equipment produced. Studies have shown that pulse interference effects on the quality of the low voltage power line carrier communication maximum. Literature statistics, intensity pulsed interference up 40dBuv.
