In the recent past power line communication has emerged as an attractive choice for high speed data transfer and is looked upon as inexpensive and reliable media suitable for broadband internet access, home and office automation, in-vehicle data communication etc. In this paper we present an architecture for the physical layer of a PLC transceiver based on Orthogonal Frequency Division Multiple...

The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and telecommunication markets has spurred the idea of using and commercializing the power networks for a range of new communication applications an...

The development of broadband wireless communication systems must cope with various performance-limiting challenges that include channel fading as well as size and power limitations at the mobile units. As a promising method dealing with these challenges, space-time coding is effective in supporting reliable, high-data-rate transmissions: the major goal in broadband wireless communications. A su...

This paper focuses on design of smart home control system based on powerline communication. Power line communication (PLC) technology is proved to be useful for control applications. It is most widely useful in home automation, automotive and internet access applications. The aim of the project is to design a power line communication modem Circuit to monitor and control the home appliances. Thi...

Power Line Communication has been considered as a good candidate for “the last mile” solution and for home networking. However Power line is worse than other wired transmission medium due to its noise. This paper introduces power line channel modelling and to realize reliable data communication over PLC. This paper carries the first Power line Channel properties and noise behaviour. This paper ...

AbstractBridging and Transmission of VDSL2 broadband over power lines has received considerable attention recently to cater to broadband distribution within the premises of a residence. Power lines are fundamentally different from telephone lines both in topology and load impedance. Power lines have a thicker gauge and shorter straight lengths, apart from a large number of bridge taps (BT) with...

This paper presents the design and electromagnetic characterization of a 3D-printed 2-way broadband power divider intended to work in RF band from several hundred MHz up few GHz. The is based on use helical-microstrip transmission line segments. Two different topologies tapered segments are considered prior deciding final divider. characteristic impedance profiles both analyzed by means simulat...

This letter presents the synthesis of a broadband rat-race consisting of a miniaturized broadband rat-race hybrid and transmission line cascades. This broadband technique involves connecting a cascade of transmission lines with lengths equal to a quarter of the wavelength at the design frequency to each port of a previously proposed rat-race hybrid. Butterworth and Chebyshev performances of the...

Home users are in need for broadband-communications access globally. Broadband power-line transmission has advanced throughout the last decade, and it is going to be a mature last-mile access in the near future. Meanwhile, indoor optical wireless communications through lighting LEDs has been investigated recently. Suitable channel models are proposed for each of these systems, and the correspon...
