Design of Optimal Entropy-constrained Successively Refinable Unrestricted Polar Quantizer for Bivariate Circularly Symmetric Sources

This paper focuses on the design of entropy-constrained successively refinable unrestricted polar quantizer (EC-SRUPQ) for bivariate circularly symmetric sources. The proposed algorithm is globally optimal under the constraint that the magnitude quantizers’ thresholds are confined to finite sets. The optimization problem is formulated as the minimization of a weighted sum of distortions and entropies. The proposed solution consists of a series …
