Abstract
Methods and techniques are described for increasing the spectral efficiency in wireless transmission and reception. In particular, sequential portions of data are mapped onto respective modulation symbols according to a target modulation, whereby the modulation symbols include a first modulation symbol and a second modulation symbol. First and second combined symbols are generated, which includes obtaining a first and a second linear combination of the first and second modulation symbol, with the first linear combination being different from the second linear combination. The first and second combined symbols are mapped onto a respective first and second carrier and transmitted.
