Abstract
It is provided a method, comprising modulating a carrier signal based on a group of input bits comprising n input bits with n=1, 2, 3, . . . out of 2n possible groups of input bits, such that, for each of the 2n possible groups of input bits, a respective sequence of N symbols is generated, wherein N is predefined, each symbol has a same duration T, a bandwidth of the respective sequence of the N symbols is k/(N*T) with k being a real value and 0<k<N.
