Integrated Rate and Credit Feedback Control for ABR Service in ATM Networks
We propose a ow-control scheme that combines the merits of credit- and rate-based ow-control schemes by applying direct control over both bandwidth and bu er resources. The goal...

Rate Bounds on SSIM Index of Quantized Images
Abstract--In this paper, we derive bounds on the structural similarity (SSIM) index as a function of quantization rate for fixed-rate uniform quantization of image discrete cosine ...

Rate distortion analysis of leaky prediction layered video coding using quantization noise modeling
Unlike conventional layered scalable video coding, leaky prediction layered video coding (LPLC) introduces a leaky factor , which takes on values in the range between 0 and 1, to ...

Effects of Imperfect Channel State Information on Achievable Rates of Precoded Multi-User MIMO Broadcast Channels with Limited F
—We consider multi-user MIMO broadcast channels with limited feedback. A recently proposed linear precoding technique, regularized block diagonalization (RBD), is used to mitigat...

Degrees of Freedom and Sum Rate Maximization for Two Mutually Interfering Broadcast Channels
— In this paper, we derive a precise expression of spatial degrees of freedom (DOF) for two mutually interfering broadcast channels (IFBC) as a function of arbitrary numbers of t...
