FIR filters obtained with the classical L/sub 2/ method have performance that is very sensitive to the form of the ideal response selected for the transition region. In this paper we propose a means for selecting the unknown part of a complex ideal response optimally. By selecting a proper L/sub 2/ criterion and using variational techniques we succeed in minimizing the criterion with respect to the ideal response and thus obtain its corresponding optimum form. The complete solution to the problem can be obtained by solving a simple system of linear equations suggesting a reduced complexity for the proposed method. Using the optimum form of the ideal response we also propose a new suboptimal method for the design of weighted FIR filters. Design examples are presented to illustrate the performance of the proposed method.

The problem of estimating the relative position of an underwater maneuvering target is treated as an estimation problem when an unknown and time varying bias is present in the plant noise process. Pilot-initiated maneuvers are modeled as impulsive unknown inputs affecting the bias term at times unknown to the observer. A new algorithm, capable of efficiently handling the problem of state estimation with time varying unknown bias, is derived by using the Lainiotis multimodel partitioning theory coupled with conventional constant bias estimation algorithms, Simulation results show that the proposed algorithm performs very well under adverse operating conditions, such as high measurement noise, long target to observer range and large-scale target maneuvers.
A constraint network is arc consistent if any value of its variables is compatible with at least one value of any other variable. The Arc Consistency Problem (ACP) consists in filtering out values of the variables of ...

This paper presents a method for near-optimum synthesis of Differential Cascade Voltage Switch (DCVS) logic circuits using Ordered Binary Decision Diagrams (OBDD). The method presented produces efficient DCVS circuit structures in terms of transistor count which positively affects the circuit area and performance. The proposed method is also very practical because it produces results with short run-times on a design workstation. The paper presents experimental results that demonstrate the use and the efficiency of the proposed DCVS synthesis method. This method is the basis for a CAD tool that allows automatic synthesis of fault secure circuits based on the DCVS technology.

The problem of radar tracking a civilian maneuvering aircraft utilizing on board available measurements of the aircraft roll angle is addressed. Two algorithms belonging to the family of adaptive multimodel partitioning algorithms are designed for this problem and evaluated via simulation experiments with regards to their performance. It is found that these algorithms perform very well in tracking a maneuvering aircraft, and, naturally, far better than previously reported non-adaptive algorithms.< >
