Abstract
A transmitter for transmitting a data transmission signal in a reception area is provided with an input for receiving an information signal (IS) to be transmitted, a coding—and/or modulation unit for coding and/or modulating the information signal with a certain coding—and/or modulation scheme into the data transmission signal, and an output for supplying the data transmission signal, and an output for supplying the data transmission signal. In accordance with the invention, the coding—and/or modulation unit is adapted to code and/or modulate the information signal with n different coding—and/or modulation schemes (n≥2), and further is adapted to transmit an additional information signal by changing between these n coding—and/or modulation schemes. The invention also relates to a receiver for receiving the data transmission signal transmitted by the transmitter.
