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 …

Performance Analysis of Signcrypt and Cryptsign on Joint Signatures
Abstract: Mobile commerce is becoming common nowadays as it looks more convenient for a user to pay through their mobile phones rather than through other electronic payment systems and it reduces frauds in electronic payments. This paper describes the performance analysis of sign then encryption and encryption then sign of the messages on joint signature scheme. Asymmetric encryption/decryption is applied along with signature generation and verification to make it secure and …

Wavelet Reduced-Order Observer-based Adaptive Tracking Control for a Class of Uncertain Nonlinear Systems
Abstract: This Paper investigates the mean to design the reduced-order observer and observer-based controllers for a class of uncertain nonlinear systems. A new design approach of wavelet-based adaptive reduced-order observer is proposed. The proposed wavelet adaptive reduced-order observer performs the task of identification of unknown system dynamics in addition to the reconstruction of states of the system. Owing to their superior learning capabilities, wavelet networks are employed in this work for …
