ABSTRACT:
The modulation method and system of the presented herein involves mapping data onto a constellations comprising a set of concentric circles in a two-dimensional plane, one dimension for the amplitude and one for the phase. The phase dimension is coded differentially, while the amplitude dimension is coded coherently. The circles in each constellation may contain equal number of points, and in other embodiments more points may be used on the outer circles. The data may be coded with dual Trellis codes, one code for the phase data and another code for the amplitude data.
