Optimized APSK bit allocation for satellite communication

In this paper a novel optimal bit allocation for APSK modulation is proposed. Optimization is done by GA according to the satellite channel error sensitivity of the data. Furthermore, a new bit mapping is proposed for 16-APSK and 32-APSK. Results show the improvement of the proposed scheme with respect to the state of the art of the APSK modulation.
