In this paper, we argue that only sufficient increase in distance between the nodes which can virtually disconnect the graph is necessary instead of the physical disconnection of the network to identify the key players in a network. A procedure is described for finding sets of key players in a social network. A key assumption is that the importance of a node v not only depends on the cohesion of its...
This paper presents an implementation of the total-field/scattered-field (TF/SF) technique in the 2-D LOD-FDTD method. The presented TF/SF implementation can be performed either by the field correction or equivalent current source approach to zone the entire FDTD lattice into the TF and SF regions. Both approaches produce similar update equations, although the latter approach is simpler to implement...
As adoption of system-level hardware design is increasing in industry and academia, accurate power estimation at this level is becoming important. In this paper, we present a system-level power estimation methodology, which is based on a high-level synthesis framework and supports sufficiently accurate power estimation of hardware designs at the system-level. For early and accurate power estimation,...
Multimedia applications are becoming even more demanding. Hence, the next generation codecs invariably should be floating point compliant. With the field programmable gate arrays (FPGAs) technology getting mature, more and more signal processing applications are finding their niche in FPGAs. Current generation FPGAs have got hardware multipliers. However, these are general purpose multipliers and...
In this paper, performance of OFDM digital communication systems have been analyzed over correlated Nakagami-m fading channel using maximal ratio combining (MRC) diversity at the receiver. We have studied statistical characteristics of inter-carrier-interference over correlated Nakagami-m fading channel and also presented signal to interference noise ratio (SINR) over correlated Nakagami-m fading...
