In the DVB-T2 digital terrestrial television standard a transmitter signature can be included in order to provide a unique identification to each of the transmitters in the network. This feature is optional and it can be exploited for many other appl

The 26 MHz band is currently allocated for international broadcasting by means of the ionospheric propagation. However, sky waves are strongly dependent on the ionosphere conditions and signal reception is not always possible. As a consequence, this
