Modified Binary Firefly Algorithm (MBFA) for Optimal Allocation of Spectrum in Cognitive Radio Systems
Abstract: Spectrum bands are nature’s communication highways which are highly congested now-adays. To overcome this problem, dynamic allocation of spectrum is under consideration over the current fixed spectrum allotment policy. In dynamic allotment, various optimisation methods can be applied for achieving the best possible spectrum allotment during handover so that the better quality of service can be given to cognitive users with the simultaneous improvement in spectrum utilisation. This study focuses …

Designing of QMF Bank
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Quadrature mirror filter (QMF) banks have been of great interest during the past decade. These filters find application where a discrete signal is to split into a number of consecutive bands in the frequency domain, so that sub-band signal can be processed in an independent manner and sufficient compression may be achieved. Typical processing includes under sampling the sub-band signals, encoding …
