Coding and Modulation for Power-Line Communications

چکیده
We describe a transmission scheme combining 4-FSK modulation with diversi&'&d coding to make the transmission over power lines robust against permanent frequency disturbances and impulse noise. We use simple non-coherent detection and derive the corresponding error correcting capabilities of the scheme. Since we use 4-FSK, the scheme is in agreement with the existing CENELEC norms. The scheme can be considered as a form of coded Frequency Hopping and is easy extendable to any frequency range. keywor&: modulation; power-line communications; coding.

Realization of Simulation Software for Power Line Communications
A simulation software is presented for estimating the performance of a low voltage power line communication system, where the parameters like modulation/coding techniques, bit rate, operating frequency and transmitter power are selectable. The simulation software estimates the BER performance in a over low-voltage power line channel, where the channel noise and the signal attenuation are predic...
متن کاملCoded MC-CDMA Systems for Power Line Communications
In this paper we use a channel model based on measurements from [l] to test the performance of a coded multicarrier CDMA system over the powerline channel from the secondary transformer coil to the subscriber. We focus on the different coding techniques which show that coding can make the difference under such a hostile medium. The comparison of coding, modulation types and the presencelabsence...
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 کاملEfficient low-cost DSP-based Hardware Architecture for Power Line Communications
This paper deals with an optimized hardware design and DSP implementation of a narrow band power line Modem. By considering a standard application of Residential Power Line Carrier (RPLC), a design approach is carried out to look for the best compromise between efficiency and hardware complexity. To combat further the hostile communication environments of power line-channel and to respect the a...
متن کاملCoding for a Terrible Channel
We describe coding and modulation aspects for a channel with different kinds of a-typical noise disturbances. An example of such a channel is the powerline communication (PLC) channel, but the same noise disturbances can be observed in for instance xDSL communications. The channel is assumed to suffer from background noise, impulsive noise, narrowband noise and fading. In addition, in PLC, the ...
