Abstract

Different non-uniform (probability shaping) signaling schemes are introduced in this invited paper. By transmitting symbols with different probabilities, energy efficiency (shaping gain) of traditional schemes can be improved. With constellation points selected according to Maxwell-Boltzmann distribution, ultimate shaping gain of 1.53dB can be achieved.
