  Comparison of Signal Detection Methods under Conditions of Discrete Stroboscopic Transformation

  V Karklinsh, K. Kruminsh

  Abstract

  <p>V Karklinsh, K. Kruminsh. “Comparison of Signal Detection Methods under Conditions of Discrete Stroboscopic Transformation”, “Automatic Control and Computer Sciences”, 2009, Vol.43, Issue 5, pp. 227-232.<br /> The comparison of the efficiency of discrete stroboscopic methods of noisy signal detection using statistical modeling and analytical calculations is carried out as applied to super-wide-band radar signals taken as an example. The harmonic mono-oscillation is taken as a super-wide-band radar signal model. Methods are compared in conditions of a small quantity of the samples after the additional processing of the transformed signals with a correlation filter.</p>

  Minimax Method in Optimizing Energy Consumption in Real-Time Embedded Systems

  A.Baums

  Abstract

  <p>A.Baums “Minimax Method in Optimizing Energy Consumption in Real-Time Embedded Systems” “Automatic Control and Computer Sciences” - Allerton Press, Inc., Vol. 43, Issue 2, 2009, pp.57–62.<br /> The main principles of the minimax method designed for solving energy consumption optimization problems in real-time embedded systems are presented. Results of comparing ways to minimize energy consumption in systems with on-line minimax and off-line DVS/DFS scheduling are given. In terms of energy consumption minimization, the minimax method is shown to ensure optimal division of the task into two subtasks. The method can be applied both to systems with tasks arbitrary distributed in time and to periodic multitasking systems with rigid timing constraints.</p>
