Abstract:
A telecommunication system with a modem having a controlling module coupled to a data transmission module includes a transmitter configured to transmit channels via a communication line. The channels transport user data by use of signals with modulation having a bitload that is modifiable. The data transmission module includes an artificial noise generator coupled to the transmitter and controlled by the controlling module to inject an artificial noise into the transmitter. The artificial noise is used to influence the signals transmitted by the data transmission module to the communication line and may be added to the data signals either in the transmit time domain processing module or in the transmit frequency domain processing module of the transmitter.
