Joint Adaptive Modulation-Coding and Cooperative ARQ for Wireless Relay Networks
This paper presents a cross-layer approach to jointly design adaptive modulation and coding (AMC) at the physical layer and cooperative truncated automatic repeat request (ARQ) pro...

Explicit Codes Achieving List Decoding Capacity: Error-Correction With Optimal Redundancy
We present error-correcting codes that achieve the information-theoretically best possible trade-off between the rate and error-correction radius. Specifically, for every 0 < R...

Performance of Space-Time Codes: Gallager Bounds and Weight Enumeration
Since the standard union bound for space-time codes may diverge in quasi-static fading channels, the limit-before-average technique has been exploited to derive tight performance b...

Object-based video coding by global-to-local motion segmentation
Abstract--In this paper, we describe an object-based video compression scheme based on the derivation and efficient coding of motion boundaries. First, we recursively identify a sm...

On Dictionary Adaptation for Recurrent Pattern Image Coding
In this paper, we exploit a recently introduced coding algorithm called multidimensional multiscale parser (MMP) as an alternative to the traditional transform quantization-based m...
