Abstract

In this paper, we propose an algorithm to determine the N-dimensional optimum signal constellation design (ND-OSCD), in MMSE sense, for channel capacity achieving source distribution. The simulation results indicate that the proposed LDPC-coded polarization-division-multiplexed (PDM) ND-OSCD significantly outperforms conventional PDM-QAM (by 4.35 dB for 64-ary 3D constellation at BER of 10-7). In addition, the ND-OSCD outperforms sphere packing constellations (by 0.36 dB for 8-ary 3D constellation at BER of 10-7).
