Abstract
We present a new and simple method for combining constellation shaping and bit-interleaved turbo-coded modulation (BITCM). By considering the example of a 3-bit/dim 16-PAM BITCM, it is shown that this technique can provide shaping gains of 0.64 dB, and error performance within 1.51 dB of the continuous-input channel capacity limit is achieved.
