有耗Gray-Wyner网络的Shannon界

Shannon Bounds on Lossy Gray-Wyner Networks

Erixhen Sula, Michael Gastpar

摘要:

研究了满足保真度准则的Gray-Wyner网络。私人和率和共同率之间的权衡的上限和下限得到任意源均方误差失真。当源是联合高斯分布时,边界正好满足,从而导致速率区域的计算。当源通过加性高斯“通道”建模时,它们部分相遇。该界的灵感来自香农界的率失真问题。

英文摘要:

The Gray-Wyner network subject to a fidelity criterion is studied. Upper and lower bounds for the trade-offs between the private sum-rate and the common rate are obtained for arbitrary sources subject to mean-squared error distortion. The bounds meet exactly, leading to the computation of the rate region, when the source is jointly Gaussian. They meet partially when the sources are modeled via an additive Gaussian "channel". The bounds are inspired from the Shannon bounds on the rate-distortion problem.
