Your library or personal account may give you access

Abstract

An accelerator unit in conjunction with generalized pairwise optimization can obtain optimum geometric shaped 64QAM constellations up to 60% faster. Shaping gain and transmission distance are improved over just GPO constellations in low-to-middle SNR regimes.
