TLDR
In this article, the effects of load, frequency, line length, and distribution transformers on the performance of a power line communication (PLC) system are investigated. And the properties of home appliances used in an average Turkish household are experimentally determined.Abstract:
Power line communication (PLC) is a communications method where signals are carried across already existing power lines, rather than through other mediums such as optical fibres or radio waves. PLC has been a very important interdiscipline topic for power, communications, industrial and automation engineers and researchers since 1980s. Designing and planning optimized or standard PLC systems require information and data regarding signal attenuations, load variations and communication performance for various locations of the world which have different power networks. In this study, PLC system is modeled by ABCD matrix and simulated via electronics workbench. In order to obtain data from Turkey's power lines, signal measurements at the frequencies of 50-200 KHz are carried out. The effects of load, frequency, line length, and the distribution transformers are examined. The properties of home appliances used in an average Turkish household are experimentally determined. System performance in terms of the bit error probability is calculated for FSK modulation.read more

Time-varying power line block transmission models over doubly selective channels
TL;DR: In this paper, a discrete time-varying block channel model is proposed to capture the cyclostationary nature of the channel response, which allows for more realistic evaluation of modulation and coding strategies as well as for the design of bit loading strategies.

Power line communications
A. Majumder,Jr. Caffery J +1 more
TL;DR: In this article, the performance of power lines for high bit rate applications is studied. But, the authors focus on the power line communication, which is originally devised to transmit electric power from a small number of sources to a large number of sinks, and the first data transmission were primarily done only to protect sections of the power distribution system in case of faults.
