In underwater wireless communication networks, a large number of nodes are deployed in different forms to cover small or large areas of interest for various practical applications. The proper accomplishment of those applications depends on the number of active nodes at any time of instant. But due to the harshness of underwater environment such as high absorption, reflections, refractions, dispersion,...
The selective passivation of lower energy defects related to nitrogen clusters and impurities is demonstrated using a low temperature UV-activated hydrogenation process. This is achieved without significant removal of substitutional nitrogen. In bulk reference materials the passivation of larger low-energy defects and the passivation of background impurity states is observed to remove the well-known...
Recently, a wideband spectrum sensing scheme referred to as multiband joint detection has been proposed by Quan et al., in which a set of frequency dependent detection thresholds are optimized to achieve the best trade-off between aggregate measures of opportunistic throughput and interference to primary users in cognitive radio (CR) networks. While this scheme shows significant performance gains...
