A Signal-Specific QMF Bank Design Technique Using Karhunen-Loéve Transform Approximation
Block Wavelet Transforms (BWTs) are orthogonal matrix transforms that can be obtained from orthogonal subband filter banks. They were initially generated to produce matrix transforms which may carry nice properties inheriting from wavelets, as alternatives to DCT and similar matrix transforms. Although the construction methodology of BWT is clear, the reverse operation was not researched. In ce...
متن کاملQmf Filter Bank Design Using Nonlinear Optimization
This research is about QMF lter bank design using nonlinear optimization methods. Filter bank has applications in areas like video and audio coding, data communication, etc. Its improvement will have important impacts in those areas. Filter bank design is a multi-objective optimization problem. One important issue in this research is that the design objectives are not unique and are con icting,...
متن کاملsignal specific successive approximation analog to digital converter
چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...
15 صفحه اولQMF filter bank design by a new global optimization method
In this paper, we study various global optimization methods for designing QMF (quadrature mirror lter) lter banks. We formulate the design problem as a nonlinear constrained optimization problem, using the reconstruction error as the objective, and other performance metrics as constraints. This formulation allows us to search for designs that improve over the best existing designs. We present N...
متن کاملA generalized parametric PR-QMF design technique based on Bernstein polynomial approximation
A generalized parametric PR-QMF design technique based on Bernstein polynomial approximation in the magnitude square domain is developed in this paper. The parametric nature of this solution provides useful insights to the PR-QMF problem. Several well-known orthonormal wavelet filters, PR-QMF's, are shown to be the special cases of the proposed technique. Energy compaction performance of a few ...
