In this work a characterization of a Wireless Power Transfer (WPT) system as a possible channel for data communication is presented. The frequency response of a real WPT system based on the principle of magnetic resonance coupling is simulated accurately using a lumped equivalent circuit model. The theoretical channel capacity of the channel is calculated(More)
In this paper, a training method for the formation of topology preserving maps is introduced. The proposed approach presents a sequential formulation of the self-organizing map (SOM), which is based on a new model of the neuron, or processing unit. Each neuron acts as a finite impulse response (FIR) system, and the coefficients of the filters are adaptively(More)
In this paper an extensive set of measurements, simulations and testing of a commercial modem are performed in an electric vehicle to evaluate the performance of PLC. The noise of the motor drive is measured and characterized in the time and frequency domains. Also, the noise generated by the AC/DC converter is measured and described. The symbol-error-rate(More)
In this paper a new technique is proposed for blind channel identification and equalization in orthogonal frequency-division multiplexing (OFDM) communication over power-lines. The proposed scheme is based on a competitive neural network which utilizes the frequency domain data in the receiver performing a nonlinear decision-directed equalization. This(More)
In this work a zero input stability analysis of the self-organizing map (SOM) learning algorithm and related unsupervised vector quantization algorithms is presented. The stability of the SOM incremental learning rule is analyzed using the theory of dynamical switched systems. The equation is demonstrated to be asymptotically stable under simple constraints(More)
In this paper the possibility to approximate the frequency response of a three-conductor power cable as a PLC channel by a two-conductor equivalent is investigated. The approximation is useful to perform faster numerical simulations of a PLC channel in the analysis or design of a three-phase PLC channel. The radius and distance between two conductors(More)
