Lifting-Based Directional DCT-Like Transform for Image Coding
Traditional 2D DCT implemented by separable 1D transform in horizontal and vertical directions does not take image orientation features in a local window into account. To improve ...

A Union Bound Approximation for Rapid Performance Evaluation of Punctured Turbo Codes
— In this paper, we present a simple technique to approximate the performance union bound of a punctured turbo code. The bound approximation exploits only those terms of the tran...

Bounds on Redundancy in Constrained Delay Arithmetic Coding
We address the problem of a finite delay constraint in an arithmetic coding system. Due to the nature of the arithmetic coding process, source sequences causing arbitrarily large ...
