Abstract: Orthogonal greedy algorithms are popular sparse signal reconstruction algorithms. Their principle is to select atoms one by one. A series of unconstrained least-square subproblems of ...

Abstract: A quasi-lossless compression algorithm for location information within civilian global positioning system (GPS) was proposed based on the analysis and comparison of performance between ...

ABSTRACT: Data compression plays a key role in optimizing the use of memory storage space and also reducing latency in data transmission. In this paper, we are interested in lossless compression ...

Add a description, image, and links to the huffman-coding-algorithm topic page so that developers can more easily learn about it.

In the continuing arms race in computer and network security, a common trend is that attackers are employing polymorphic techniques. Toolkits such as ADMmutate [17], PHATBOT [10], and CLET [5] are ...
