New Concept of PLC Modems: Multi-carrier System for Frequency Selective Slow-fading Channels Based on Layered SCCC Turbocodes

Popis výsledku v původním jazyce

The article introduces a novel concept of a PLC modem as a complement to the existing G3 and PRIME standards for communications using medium- or high-voltage overhead or cable lines.The proposed concept is based on the fact that the levels of impulse noise and frequency selectivity are lower on high-voltage lines than on low-voltage ones. Also, the demands for “cost-effective” circuitry design are not so crucial as in the case of modems for low-voltage level. In contract to these positive conditions, however, there is the need to overcome much longer distances and to take into account low SNR on the receiving side. With respect to the listed reasons, our concept makes use of MCM, instead of OFDM that is advantageous only for static transmission environments with high frequency selectivity, and the assumption of low SNR is compensated through the use of an efficient channel coding based on a serially concatenated turbo code. In addition, MCM offers lower latency and PAPR compared to OFDM. Therefore, when using MCM, it is possible to excite the line with higher power through relatively simple and cheap final stages. The proposed concept has been verified during experimental transmission of testing data over a real, 5 km long, 22kV overhead line.
