Abstract

This document discloses a solution for modulating and demodulating signals transferred over a communication channel. According to an aspect, a method comprises: storing a database for mapping rules for mapping a block of N bits into M modulation symbol phase transitions, wherein a phase transition between consecutive modulation symbols is limited to less than or equal to ∓π/2, wherein M is smaller than N, and wherein M is the smallest number required for realizing 2N different phase-transition combinations; determining an initial phase; acquiring a block of N bits and modulating the block of N bits into M phase symbol transitions from the initial phase by using bit values of the block of N bits and the mapping rules, thus acquiring M modulation symbols; performing said determining, acquiring, and modulating for further blocks of N bits, thus acquiring a sequence of K modulation symbols; allocating the sequence of K modulation symbols to sub-carriers of a multi-carrier symbol and causing transmission of the multi-carrier symbol over a radio interface.
