On coded and multi-dimensional partial response signaling

Optimal finite partial response signals based on 2 and 4 PAM have been found by Said and Anderson. The encoder is a simple discrete-time filter, whose combination of bandwidth and Euclidian distance is optimized. Here we extended the idea to the case where the modulated symbols are first encoded by a short convolutional encoder. This gives power gains of 1-3 dB while maintaining the same bandwidth

Design of mixed MPLS/OSPF routing in IP networks

In this paper we address the problem of Internet networks optimization using a mixed Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing. Since MPLS can be combined with any routing protocol there appeared an idea of coupling IP streams routed via OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined rout

A CNN hardware-only approach to speed measurement

Vision sensors are of increasing interest for non-destructive, remote measurements in industrial as well as consumer products. Their operation is based on intelligent techniques for image understanding, followed by robust quantification of the detected phenomenon. A well-known application area is movement detection and isolation. This paper discusses how movement can be detected and quantified by

A History of the Future: Concepts for telling the story of online PR

The internet has had an impact on public relations that goes well beyond significant adjustments in practice made in response to technological change. Mirroring the emergence of ”Web 2.0” platforms, the discipline is increasingly articulating its purpose and culture through discourse associated with social media. Concepts such as transparency, authenticity, conversation and engagement can be inext

On nested convolutional codes

Nested convolutional codes are a set of convolutional codes that is derived from a given generator matrix. The structural properties of nested generator matrices and nested convolutional codes are studied. A method to construct the set of all (rational) minimal generator matrices of a given convolutional code is presented. Nested convolutional codes derived from equivalent minimal generator matric
