Formulation of Multiwire Magnetic Transmission-line Theory
Timeand frequency-domain theory of multiwire magnetic transmission lines is presented for the first time. The familiar theory of electric multiconductor transmission lines (MTL) is based on the manipulation of two matrices, the longitudinal impedance and the transverse admittance. However, for magnetic MTLs, the key matrices are the transverse impedance and the longitudinal admittance. It is sh...
متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...
متن کاملA Model for 10kV Overhead Power Line Communication Channel
In order to achieve reliable and high-speed 10kV power line carrier communications, it is necessary to study the characteristics of channel. Based on the multi-conductor transmission line theory, the chain matrix channel model is established. A lumped parameter model of distribution transformer is proposed from impedance measurement in the frequency range 50-500kHz. The terminal voltages and cu...
متن کاملIntegrated Communication Model of the Hv Power-line Channel
The presented integrated communication model corresponds to a computer simulation model used for computation of communication characteristics of an arbitrary HV overhead power-line channel. The simulated characteristics are suitable for analysis of the digital communications techniques application for highspeed data transmission over HV power lines. The integrated model is implemented as Matlab...
متن کاملSurvey of Power Line Communication
In this paper a survey of power line communications has been presented. As power line distribution networks are available in almost each building that is mainly used for the supply of electrical power, it will be very interesting if such media could be used for the transmission of data. The demand of low cost telecommunication, broadband and access to internet services is increasing day by day ...
