A framework of APSK constellation labeling design for satellite transmission

In this paper, the framework of amplitude phase shift keying (APSK) constellation labeling design for satellite transmission is proposed. It consists of two steps, the constellation design and the joint phase-labeling optimization. Both iterative and non-iterative demapping scenarios are considered in the design framework. The proposed APSK constellation labeling exhibits a low peak-to-average power ratio and achieves a considerable performance gain compared with its counterpart approved by the consultative committee for space data systems, as verified by both the mutual information analysis and bit error rate simulation.
