Ways of transmitting information via the cable power line

Abstract

Purpose. Study the possibility of transmitting information via the cable power line of using NLS based on pseudorandom sequences(PRS). Methodology. At the moment there are two methods to study extensive power networks. The first method is analytical one, which makes it impossible to obtain all the necessary information about the physical phenomena occurring in the network, since with non-stationary objects the input resistance and the overall of the signal level are continuously varied. The second method is electrical simulation, which provides ample opportunities to explore the different modes of operation. This takes into account all the phenomena affecting the transmitted signal. Under the electric modeling implies the creation of a set of active and reactive resistances of the equivalent cell line which is typed in the network diagram which is electrically equivalent to a real network located in the mine. To achieve this goal it is necessary to develop a laboratory setting that allows to generate a modulated NLS based on the PRS of Huffman coding, which will be sent to the communication line, and then transmitted to the receiver for subsequent correlation and integration. The experimental data at different levels of noise in the communication line will be recorded for further statistical processing.
