Since Limís 1986 paper on the frequency-response masking (FRM) technique for the design of FIR digital Ýlters with very small transition widths, the analysis and design of FRM Ýlters have been a subject of study. In this paper, a new optimization technique for the design of FRM Ýlters is proposed. Central to the new design method is a sequence of linear(More)
—In this paper, minimax design of infinite-impulse-response (IIR) filters with prescribed stability margin is formulated as a conic quadratic programming (CQP) problem. CQP is known as a class of well-structured convex programming problems for which efficient interior-point solvers are available. By considering factorized denominators, the proposed(More)
The so-called receiver operating characteristic technique is used as a tool in an optimization procedure for the improvement and assessment of a filter-based methodology for the location of hot spots in protein sequences and exons in DNA sequences. By optimizing the characteristic values of the nucleotides, high efficiency as well as improved accuracy can(More)
— One of the most attractive features of ultra-wideband impulse radio is the collection of rich multipath with the transmission of ultra-short pulses. Exploiting the rich multi-path diversity with channel estimating Rake receivers enables significant energy capture, higher performance and flexibility than suboptimal receivers. Although data-aided (DA)(More)
