Abstract: A new polar coding scheme for higher order modulation is presented. An encoding method is proposed such that in combination with Gray labeled amplitude shift keying the channel input symbols have a desired non-uniform distribution,… read more here.

Abstract: In this paper, the probabilistically shaped polar-coded multiple-input multiple-output free-space optical (MIMO-FSO) communication system with or without spatially correlated (SC) fading is investigated to improve transmission performance. The designed shaping-polar encoder can flexibly generate three… read more here.
