Joint Source Coding and Higher-Dimension Modulation

Free registration required

Executive Summary

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. Typical inputs to a source encoder have unequal prior probabilities. For example, some alphabets have higher prior probabilities than other alphabets in an alphabet stream.
