摘要：
Non uniform constellations have been recently included in the new terrestrial broadcasting system ATSC 3.0, providing better performance than the uniform ones. However, for high order constellations, the complexity in the demapper grows as the number of constellation points do, being necessary to reduce the number of degrees of freedom in the constellation design process. The goal of this paper is to present a set of optimal high order non uniform constellations which provide higher gain than the ones proposed for the ATSC 3.0 system with low demapping complexity.
