A New Algorithm for Designing FIR-Filters with Small Word Length

by Nitin Ahuja, Ulrich Heute, Christian Richter
"... Abstract. We present a new algorithm for designing FIR-filters with small word-lengths. The core of our algorithm is a potential function taken from the specefic area of randomized algorithms used in combinatorial optimization. We formulate the problem of finding quantized, integral filter coefficie ..."

A Modification of Deriche's Approach to Edge Detection

by Stefan Lanser, Wolfgang Eckstein, Technische Universitit Mtinchen - In: 11th International Conference on Pattern Recognition , 1992
"... In 1983 Canny presented criteria for measuring the quality of edge detectors and derived an optimal FIRFilter for step edges by optimizing them. Four years later Deriche proposed an approach to edge detection based on Canny design utilizing IIR-Filters which can be implemented very efficiently recur ..."

Filter Optimization for Carrier-Frequency- and Timing-Offset in Universal Filtered Multi-Carrier Systems

by Xiaojie Wang, Thorsten Wild, Frank Schaich
"... Abstract — Universal Filtered Multi-Carrier (UFMC) is a novel multi-carrier modulation technique which can be seen as a generalization of filtered OFDM and filter bank based multi-carrier (FBMC-FMT). Being a candidate waveform technology for 5G wireless systems, it combines the simplicity of OFDM wi ..."

by optimizing the FIR-filter, taking carrier frequency offset into account. In this paper, we optimize the FIR-filter design in UFMC by taking both carrier frequency and timing offset into account in an uplink multi-user FDMA scenario. From the simulation results, up to 3.6 dB SIR improvement can be achieved

A Contribution to the Design of Digital Three-Dimensional FIR and IIR Cone Filters

by Gerhard Runze, Peter Steffen - Proceedings of 3D Image Analysis und-synthesis '96 , 1996
"... This paper extends a 2-D filter design method, which was introduced in [1], to the third dimension. The advantage of the proposed method to other known designs is that arbitrary 3-D frequency responses can be designed with the same algorithm. In addition the designed filter can be optimized by an ar ..."

by an arbitrary weight function with respect to a single design parameter. Furthermore our method is not restricted to FIR-filters. Also stable IIR-filters can be easily designed. The first part of this paper describes the general design method, the second proposes a way to optimize the frequency response

SIGNAL PROCESSING

by unknown authors , 1995
"... In this paper, an effective approach is proposed for designing discrete coefficient 2-D FIR digital filters for sampling structure conversion. After obtaining the initial continuous solution, the conventional Lagrange multiplier approach as-sociated with an appropriate tree search algorithm is used ..."
Abstract - Add to MetaCart
iteratively to optimize the remaining unquantized coefficients of the designed filter in the least-squares sense when one or more of the coefficients take on discrete values, till all of the filter coefficients are quantized. The method is simple and the performance is comparable with that of the existing
