Abstract
Constellations () arranged in a concentric circle pattern provide simplified control of modulated communication. A plurality of concentric circles () with defined points () include convolutionally coded and uncoded bits. Constellation patterns having three or four concentric circles () are provided. A magnitude error for each of the points () allows for deviations during communication. The constellations () provide efficient communication using non-linear channels.
