Abstract: It is characterized by the assignment of a local transmission identifier to each link and a decoding of the information based on the local identifier of the assigned link and on the unequivocal identifier sent by the transmitter in its transmission period. It permits multiple links to be established between stations of a telecommunications network, in a way that is unicast (towards a single recipient) or multicast (towards multiple recipients) independently of the type of network or system used in the communication. It is applicable to telecommunication systems which apply an addressing system for the connection of stations and displays the advantages of minimizing the data overload due to the headers, facilitating the establishment of connections between two or more stations and making the addressing of the packets within the same network more flexible.

Abstract: This permits the transmission of signals over the electricity network in such a way that the spectral density of power is adjusted to the regulations in the current rules by means of the possibility of introducing notches in transmission in an efficient manner. It is characterised by the adjustment of the power in one or more carriers of an OFDM signal for generating these notches, through the use of IDFTs of at least 1024 points (if the IDFT is complex) or at least 2048 points (if the IDFT is real) and through the use of a window to multiply the symbols to be transmitted in time.
