Abstract

The increasing use of hierarchical modulation techniques having fixed parameters with non-binary Turbo codes has risen the interest to obtain optimized parameters with a view to enhance the error performance. In this paper, a derivation of optimum parameters for performing Hierarchical modulation with16-QAM integrated with triple-binary turbo codes have been performed. The validation of the enhanced performance achieved using Hierarchical modulation with optimized parameters has been presented using EXIT charts. Additionally, a classification using K-NN method has been presented. The technique is used to forecast the optimized parameters at every Eb/N0. Results demonstrate that Triple-binary turbo codes with triple length of 152, code-rates = 1/3 and 1/2, and 16-QAM provide an average gain of 0.4 dB.
