Opposite to many other communication channels the powerline channel does not represent an additive white Gaussian noise (AWGN) environment; in the frequency range from some hundred kilohertz up to 20 MHz it is mostly dominated by narrow-band interference and impulsive noise. After a basic classification of the different types of noise the properties of(More)
For the use of the mains networks as high speed data path for Internet, voice and data services carrier frequencies within the range from 500 kHz up to 20 MHz must be considered. The development of suitable communication systems and the planning of power line communication networks requires measurement-based models of the transfer characteristics of the(More)
igital communications over power lines is an old idea that dates back to the early 1920s, when the first patents were filed in this area. Since then, utility companies around the world have successfully used this technology for remote metering and control. These applications, however, require only very low bit rates. More recently, there has been a growing(More)
This paper considers aspects of synchronising an OFDM system for powerline communications. A comprehensive analytical model of the demodulated signal in the receiver is derived, including all errors introduced by synchronization mismatch. The occurring errors are separated in static and dynamic distortion, thus pointing out the necessity to have the two(More)
