摘要：
The present invention relates to a method of digital modulation comprising: generating a stream of modulation symbols in order to produce a modulated signal, where said modulation symbols belong to a multi- ring digital signal constellation (200, 201, 202, 203), said multi-ring digital signal constellation having all signal points placed on at least two concentric rings (200, 201, 202, 203), whereby • a) the total number of signal points is larger than 8, • b) at least one ring has unequally spaced points (201), and • c) said at least one ring with unequally spaced signal points is constructed to form together with at least one neighbouring ring a subset of neighbouring rings (202), whereby each signal point of said subset has a unique angular coordinate modulo 2
π and whereby the angular spacing of the signal points of said subset is uniform (Δ
θ ).
