Summary: | Methods and techniques are described for increasing data rate at a high error performance in wireless transmission. In particular, each complex symbol of a sequence of complex symbols is mapped onto a respective subcarrier in a frequency division based system, which may be orthogonal or non-orthogonal frequency division multiplex. The sequence is a sequence concatenated from N sequences of complex symbols, wherein N is an integer greater than one, and each of the N sequences is a mapping of the data block onto the complex symbols of the respective sequence. The real parts of the sequence have been circularly shifted by a first number, cRe, of elements, and/or the imaginary parts of the sequence have been circularly shifted by a second number, cIm, of elements, wherein cRe and cIm are different integers greater than or equal to zero. |
