Joint Source Coding and Higher-Dimension Modulation

Abstract

This paper proposes a novel joint source coding and modulation scheme. The modulation constellation points are selected according to their prior symbol probabilities for better bandwidth as well as better bit error rate performance. Both the analysis and simulation results are presented to verify that the proposed scheme can achieve better performance than the conventional disjoint source coding and modulation schemes if the modulation and source coding are designed jointly and efficiently.

Hybrid Multi-Dimensional Modulation for Gaussian and Fading Channels

“…An exact symbol error probability calculation for arbitrary three-dimensional constellations was examined in [7]. Related works on multidimensional modulation include [8], [9].…”
