The response of power-line channels demonstrates a time-varying behaviour, synchronous to the mains, whose origin is the dependence of the impedance of some electrical devices on the mains voltage. This paper aims to present a novel decision-directed estimation method based on the Self-Organizing Map (SOM). The proposed method reveals to be very effective in the presence of time varying channels. Numerical simulations for different realistic indoor power line networks and the comparison between different approaches reveal the potential of the proposed estimation method.

This work deals with the planning of the broadband power line communications networks. The design process of these networks is subdivided into two main sub-problems; namely the Generalized Base Station Placement problem and the Channel Allocation Problem (CAP). This CAP is the focus of this work. It is modelled as a Multi-objective Optimization problem and solved by multi-objective optimization algorithms. Based on our previous investigations in this field, we propose in this paper the application of a dispatching method, in order to allocate better and fairly the available set of channels to PLC cells. The advantage of this dispatching is reflected by the improved algorithms convergence. The algorithms performance is evaluated using some network reference scenarios.
