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, resulting in a shaping gain at the receiver compared with the conventional bit-interleaved coded modulation. The proposed scheme mainly affects the encoder, and the complexity increase at the receiver is negligible.
