Abstract
Devices, methods and examples concerning a concept for transmitting an information symbol from a symbol alphabet (I0; I1; I2; I3). For a first information symbol (I1) from the symbol alphabet, a first signal sequence (S1) is transmitted. For a second information symbol (I2) of the symbol alphabet, a second signal sequence (S2) is transmitted. A cross-correlation between the first signal sequence (S1) and the second signal sequence (S2) is lower than a predetermined cross-correlation threshold (Ψthreshold). For a third information symbol (I3) of the symbol alphabet, a third signal sequence (S3) is transmitted such that both a cross-correlation between the third signal sequence (S3) and the first signal sequence (S1) and also a cross-correlation between the third signal sequence (S3) and the second signal sequence (S2) are above the predetermined cross-correlation threshold (Ψthreshold).
