Abstract

This paper discusses a new concept which entails PLC nodes to on-line determine their working frequency that best fits the local conditions. This optimization often is inevitable for PLC to establish reliable link in many situations. For access network a wide frequency range is proposed for this frequency optimization which exceeds current narrow band and broadband frequency separation. As an example a wide band digital front end design combined with equivalent complex base-band technique is presented which is able to cover a frequency range between 150 kHz-10MHz and support OFDM signal with various bandwidths. A possibility to use a short preamble signal for initial frequency selection has been discussed.
