Abstract
A method of digital modulation comprises generating a stream of modulation symbols in order to produce a modulated signal. The modulation symbols belong to a multi-ring digital signal constellation having all signal points placed on at least two concentric rings. The total number of signal points is larger than 8, and at least one ring has unequally spaced points constructed to form together with at least one neighbouring ring a subset of neighbouring rings. Each signal point of the subset has a unique angular coordinate modulo 2π and the angular spacing of the signal points of the subset is uniform.
