A Generalized Pairwise Optimization Accelerator Unit for Designing Geometric Shaping 64-QAM (Th1A.17)

Presenter: RACHATA MANEEKUT, KDDI Research Inc.

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.
