Performance Comparison of Terrestrial DVB Detection using LDPC and Turbo Codes
Published In: GJCST Part: E: Network, Web & Security Volume: 13 Issue: 8
Last-generation and future wireless communication standards, such as DVB-T2 or DVB-NGH, are including multi-antenna transmission and reception in order to increase bandwidth efficiency and receiver robustness. The main goal is to combine diversity and spatial multiplexing in order to fully exploit the multiple-input multiple output (MIMO) channel capacity. Full-rate full-diversity (FRFD)...

Improve Relevancy of Object Oriented Class Cohesion Metrics with Inheritance
Published In: GJCST Part: C: Software & Data Engineering Volume: 13 Issue: 7
Cohesion is a very important quality attribute in software. As we know that there are number of cohesion metrics are proposed in the literature to measure the cohesion of software systems. These metrics gives undefined values for a large number of classes which comes under special cases. Because of this reason, these metrics became non-applicable for these classes as they are unable to g...

Secured Localized Broadcasting in Wireless Ad-Hoc Networks
Published In: GJCST Part: E: Network, Web & Security Volume: 13 Issue: 8
Broadcasting, one of the fundamental operations of the wireless ad-hoc networks, can be implemented using two approaches i.e static and dynamic. In broadcasting a node disseminates a message to all other nodes within the network. Usually in static approach the forwarding or non-forwarding status of the node is determined by a globally known priority function and local topology informatio...

Image Mosaicing with Invariant Features detection using SIFT
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5
There are situations where it is not possible to capture larger views with the given imaging media such as still cameras or video recording machines in a single stretch because of their inherent limitations. So to avoid such conditions a term Image Mosaicing comes into play. This Paper presents a complete system for mosaicing a group of still images with some amount of overlapping betwee...
