On concentric permutation code based vector quantizer design
Mohit Kumar Sharma, A. Rajesh, Prabin Kumar Bora · 2012
We address an important issue in the design of concentric permutation code based vector quantizers to select the optimal integer partitions. We establish that, for concentric permutation code based vector quantizers, the optimum integer partitions exhibit monotonicity with its index. In addition, a reduced complexity encoding scheme for concentric permutation code based vector quantizers is presented.
