Power lines at distribution level can represent an attractive medium for broadband delivery. They reach more homes than coaxial cable systems or telephone lines and hence broadband can be delivered everywhere where these lines reach. This paper presents characterization of power line channel for digital data transfer over low voltage distribution lines system. The work is based on the power line characterization using scattering matrix approach. It is demonstrated that varying network topologies of indoor power line channel can be modelled using two-port network theory for accurate results. The comparison of transfer function is obtained for two wire and coaxial cabling techniques. The simulations are performed to observe and reveal that the characteristics of channel depend on frequency, termination type, and cable type. The authors also make an effort in the direction of designing and simulating a typical coupling circuit under different load conditions.

Multimedia applications like high definition digital television push the manufacturers to increase available bandwidth mainly in Powerline Communication (PLC) links. Because of this needs in this work a PLC link control is developed to maximize the information rate meanwhile the bit error rate (BER) is maintained under a desired reference limit. The developed control system has a unique variable called minimal total distance and the feedback loop signal is estimated from the low-density parity check (LDPC) decoder iterations. These mentioned characteristics enable a fast and simple control scheme. In order to evaluate the control system behavior a complete Powerline (PL) link was modeled in a matrix form and simulated with a measured PL channel model and with an additive white Gaussian noise (AWGN) channel. The implemented PL link reaches 570Mbps in AWGN. Finally the BER control shows a good response under a severe random walk SNR channel variation.
