A transmitter for transmitting a data transmission signal and a receiver for receiving a data transmission signal, each of which can switch between coding and / or modulation schemes depending on a side information signal,

摘要

The present invention relates to a transmitter for transmitting a data transmission signal in a reception area. The transmitter includes an input 102 for receiving an information signal to be transmitted, a coding and / or modulation unit 104 for coding and / or modulating the information signal to a data transmission signal via a specific coding and / , 106, and an output 108 for supplying a data transmission signal. According to the present invention, the coding and / or modulation unit is adapted to code and / or modulate the information signal via n different coding and / or modulation schemes (n = 2), such n coding and / (Fig. 1, Fig. 2). The present invention also relates to a receiver for receiving a data transmission signal transmitted by a transmitter.
