论文摘要
在本文中,研究了灰色智者有损源编码系统的速率延伸理论。对于共同高斯分布式源,我们在二次失真的约束下建立了速率函数的表达式。使用拟议的利率 - 延伸函数,可以方便地计算速率区域的任何角点。我们以Wyner的常见信息为例,并提供了解决此问题的一般而简单的方法。通过分析速率函数,本文还介绍了辅助随机变量和源的辅助随机变量的速率和协方差矩阵。
In this paper, the rate-distortion theory of the Gray-Wyner lossy source coding system is investigated. For the case of jointly Gaussian distributed sources, we establish an expression for the rate-distortion function under the constraint of quadratic distortion. Using the proposed rate-distortion function, any corner point on the rate-distortion region can be conveniently calculated. We take Wyner's common information as an example and provide a general and simple method to solve this problem. Through the analysis of the rate-distortion function, the rate on each layer and covariance matrix of auxiliary random variables and the sources are also presented in this paper.
