Abstract:
A simple construction for a family of non-uniform APSK constellations by the radial isomorphism between squares to circles is provided. The mutual information values indicate gains of at least 0.5 dB up to 1.5 dB with respect to the state of the art, such as the DVB-S2X constellations with 256 symbols. The invention also provides for a low-complexity detector of high-order modulated signals.

Claim (Index 16):
A data reception device comprising a receiver, a detector and at least one memory element, the device being configured for:\n the receiver receiving a modulated signal, wherein said signal has been modulated at a transmitting node using a first M-ary signal constellation, the symbols of said first signal constellation being distributed on a plurality of C concentric circles; the detector detecting each symbol of said received modulated signal; wherein said first M-ary signal constellation is such that there exists a corresponding second M-ary quadrature amplitude modulation, QAM, signal constellation having an equal plurality of C concentric squares, wherein a symbol on a given circle of the first signal constellation bijectively maps to a symbol of a corresponding QAM square, and wherein the detection means are further configured for i) detecting each symbol in the modulated signal using the characteristics of the second QAM signal constellation.
