This paper introduces a new technique for combining constellation shaping and bit-interleaved turbo-coded modulation (BITCM) over additive white Gaussian noise channel. The proposed scheme consists of serial concatenation of a binary turbo code, short-length binary shaping code, and mapping function using Gray labeling. The corresponding receiver is made up of four blocks (demapper, shaping decoder, and two constituent RSC decoders) exchanging extrinsic information in order to optimize error… CONTINUE READING
