Transmitter for transmitting a data transmission signal and receiver for receiving the data transmission signal each of which can switch between coding and/or modulating schemes in dependency of an additional information signal

A receiver for receiving a data transmission signal, the receiver being provided with at least the following:

• an input for receiving the data transmission signal;
• a demodulation and decoding unit for demodulating and decoding the data transmission signal with a certain demodulation and decoding scheme into an information signal;
• and
• an output for supplying the information signal to a receiver,
• wherein the demodulation and decoding unit is adapted to demodulate and decode the data transmission signal into the information signal, which is coded and modulated with n coding and modulation schemes, where n is an integer for which holds:
• n>2,
• wherein the receiver is further adapted to derive, from one or more switching-overs between the n coding and modulation schemes of the received data transmission signal, an additional information signal and a feedback signal to supply the additional information signal and the feedback signal to the output supplied to the receiver, and
• wherein the receiver sends the feedback signal, which is different from the additional information signal, to a particular transmitter, the feedback signal being structured to trigger the particular transmitter to switch from using a first modulation scheme to modulate the information signal to using a second modulation scheme to modulate the information signal, and wherein the receiver also sends the additional information signal to the particular transmitter, the additional information signal triggering the particular transmitter to switch from using a first coding scheme to code the information signal to using a second coding scheme to code the information signal.
