Low-Complexity Maximum Likelihood Detection of Orthogonal Space-Time Block Codes
Abstract— In this paper, we propose a low complexity Maximum Likelihood (ML) decoding algorithm for orthogonal spacetime block codes (OSTBCs) based on the real-valued lattice rep...

Water Level Detection for Functionally Layered Video Coding
This paper proposes a new type of layered video coding especially for the use of monitoring a river or a water channel. A sensor node of the system decomposes a video signal into ...

CoCo: coding cost for parameter-free outlier detection
How can we automatically spot all outstanding observations in a data set? This question arises in a large variety of applications, e.g. in economy, biology and medicine. Existing ...

A Note on Error Detection in an RSA Architecture by Means of Residue Codes
Recently, various attacks have been proposed against many cryptosystems, exploiting deliberate error injection during the computation process. In this paper, we add a residue-base...
