Performance Analysis for Vector Quantization of Distributed Source

To study the quantitative relation of dimension and complexity.The rate and distortion of distributed source vector quantization are characterized and analyzed through the point density function of a quantizer.The function of rate,distortion,dimension is then derived,and the asymptotic performance of vector quantization is analyzed.The function of dimension and performance is then obtained.Simulation results showed that rate-distortion performance can approach WynerZiv bound gradually with increasing dimension.The performance of distributed source vector quantization can approach Wyner-Ziv bound in the lower dimension case.So performance requirements can be met by low-dimension quantizer of less complexity.
