Abstract
A system for embedding phase and amplitude into a real valued unipolar signal suitable for intensity modulation (IM) by optical transmitters. The system includes a complex-to-unipolar conversion engine configured to receive complex symbols in Cartesian format and convert the complex symbols from the Cartesian format to a polar coordinate format and generate real valued unipolar symbols including embedded phase and amplitude information of complex symbols in the Cartesian format.
