Abstract :
Shannon´s entropy can be obtained by Sterling´s approximation of thermodynamics entropy, indicating that statistical physics energy minimization methods are directly applicable to the signal constellation design. We demonstrate that statistical physics inspired energy-efficient coded-modulation significantly outperforms conventional PDM-QAM.
