METHOD FOR THE SPECTRAL CONFIGURATION OF SIGNALS MODULATED BY MEANS OF ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) FOR AN ELECTRICAL NETWORK

摘要

The invention relates to a method for the spectral configuration of signals modulated by means of orthogonal frequency division multiplexing (OFDM) for an electrical network. The invention is characterised in that the sampling frequency of the digital-analogue converters of the transmitter and analogue - digital of the receiver is maintained, such that the bandwidth, the spectral position of the OFDM signal, the spectrum shape of the transmitted OFDM signal, the spectrum level of the OFDM being transmitted or any combination of same can be varied in a selective and independent manner for the transmissio n path and the reception path. In this way, the spectrum of the OFDM signal ca n be configured in terms of bandwidth, frequency position and transmitted powe r, so that it can be adapted to the relevant standards in different countries a nd to the channels encountered in the different sections of the electrical network. Moreover, all of the aforementioned changes are made without affecting the analogue components of the system, i.e. retaining the same physical implementation.
