Abstract

The new iterative nonuniform polar quantization method is presented in this paper. The decision levels and the reconstruction levels are determined by this iterative method as well as the number of points on levels. The quantization mean-squared error (MSE) is used as the criterion for optimization. We also present the exact method for the error probability determination per signal constellation symbol, which is obtained by this quantization method. The error probability for nonequiprobable symbols transmission through a channel with the additive Gaussian noise is also computed
