The notion of ecological optimum is discussed as related to aquatic poikilothermic animals. Publications on the analysis of the influence of thermal factor on vital functions of invertebrates with the subsequent statement of the general pattern of optimal environmental factors are reviewed. It is concluded that the optimum includes not simply the range of the factor's values on the tolerance curve or the dose of the factor providing for the most favourable life conditions, but the oscillations of the factor within the optimum range, i.e., the a...
Abstract We deal with the optimization of a convolutional coder for a system with reduced complexity receivers used for coded continuous phase modulated signals. A code search procedure called the optimum transmitter concept is discussed. The results of the systematic code optimization procedure for convolutional codes with rates r=1/2 and r=2/3 combined with MSK, duobinary MSK and TFM signals are shown
Abstract Two linear MMSE receivers for CDMA downlink signals are studied. Code matrices are modeled as isometric and i.i.d random matrices and the performance of these receivers is studied for large spreading factors using free probability tools.
Abstract The author applies both heuristic and optimum (B&B) approaches to schedule DSP algorithms. Heuristic approach can produce a nearly optimal schedule in most of the cases. But, the effectiveness of different heuristic rules on scheduling of a given algorithm cannot be predicted in advance of the solution. Thus, it is advisable and economically practical to employ several heuristic rules schedulings and then choose the schedule that comes closest to meet desired completion time. However, it can not be claimed that the optimum schedule is...
Abstract The analysis of a new hybrid waveform designed to optimize both range and velocity resolution is described. Two modulation techniques, frequency agility and direct sequence spreading, are chosen to improve range resolution through pulse compression techniques. The frequency order in a frequency agile radar is chosen so there is at most one coincidence in frequency between the transmitted and Doppler shifted return signal. The ambiguity function is used to illustrate and compare single and hybrid modulated waveforms. It is shown that h...
Abstract Various optimum and sub-optimum filters have been added to the basic cross-correlator in order to enhance its time delay estimation capability in the presence of noise. These pre-detection filters include the Hannan-Thomson, the Eckart, the Smoothed Coherence Transform, some least-squares, and two optimum filters recently derived by the authors. Here, a quantitative comparison of all six filters has been conducted by extensive simulation for various input signal and noise ratio and signal and noise bandwidths. The results define the a...
Abstract This paper will explore the delicate balance that exists between the goals and objectives of the Marine Mammal Protection Act and those of the Magnuson Fishery Conservation and Management Act from a legal as well as a scientific point of view. Specifically, this paper will focus on the fishery management plan as a method of incorporating the mandates of both statutes in the development of multi-species, ecosystem-oriented management programs that will ensure the "optimum" coexistence of marine mammals and fisheries.
