Abstract: The present invention relates to a method for determining a signaling set, comprising: selecting a first basis function in the form of a symmetric pulse represented by an even function; selecting a second basis function orthogonal to the first basis function; wherein the second basis function is represented by an odd function having a shape determined by a variable parameter; and determining a signaling set comprising a plurality of data signals formed by linear combinations of the first and second basis functions based on a predetermined requirement of the signaling set. The invention also relates to a modulation and demodulation method using the signaling set, a device performing the modulation and demodulation method and to a system incorporating such a device.
