The present invention relates to a method for demodulating rotated constellations based on a geometrical approach. In embodiments of the present invention, a method for demodulation of the present invention is described wherein at least one geometrical transformation is applied to the received signal data and to the constellation diagram at the receiver. In one particular embodiment, the method comprises the steps of moving the set of candidate constellation points to a new reference point, rotating the moved constellation to make a line of constellation points of the rotated constellation horizontal and estimating or approximately deriving the closest constellation points with the corresponding bit being 0 and 1. |
