Low voltage power line carrier communication simulation software and simulation test system is analog carrier communication channel environment in different ways, the two systems complement each other, the former design stage for communications equipment, flexible and comprehensive simulation of the channel complex transmission characteristics; the latter stages of a communication device for debugging,...
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...
Noise power line channel is the largest low-voltage power line interference sources, it is not a simple additive white Gaussian noise, but a time-varying noise, and with different environments and change, which is mainly the work of each of the grid kinds of electrical equipment generates, including instant asynchronous impulse noise such as background noise switching power supply or generation of...
The use of semi-physical simulation platform for school laboratory and classroom building scene a lot of field measurements, analysis of power line channel transmission characteristics of the different environments, and features a three-dimensional graphic display of variable power line channel under different scenarios. At the same time in order to improve the efficiency of the data analysis, the...
Low-voltage power line channel characteristics are designed for low voltage power line carrier communication system foundation. The paper used to design and develop a system for measuring the electrical characteristics of the low voltage power line communication network used to do high, including the noise characteristics of the input impedance characteristics, signal attenuation characteristics and...
