A Wideband Adaptive Communication System, J. C. Hancock, W. C. Lindsey
A Wideband Adaptive Communication System, J. C. Hancock, W. C. Lindsey
Department of Electrical and Computer Engineering Technical Reports
The concept of an open loop Adaptive Communication link is established as one which is capable of monitoring the medium through which it must perform while simultaneously transmitting information and continuously adjusting its modes of operation so as to optimize its performance with respect to a performance criterion chosen a priori. Statistical methods are applied to the adaptive communication problem. Communicating through a random multipath channel with additive noise is considered. The transmitter is specified as one which transmits one of two possible noise-like waveforms which are assumed to be known at the receiver. At any time, it is postulated …
The Variable Gradient Method Of Generating Liapunov Functions With Application To Automatic Control Systems, John E. Gibson, D. G. Schultz
The Variable Gradient Method Of Generating Liapunov Functions With Application To Automatic Control Systems, John E. Gibson, D. G. Schultz
Department of Electrical and Computer Engineering Technical Reports
The contribution of this thesis is the introduction and development of the variable gradient method of generating Liapunov functions. A Liapunov function, V, is considered to be generated if the form of V is not known before the generating procedure is applied. Two previous attempts at the generation of Liapunov functions to prove global asymptotic stability for nonlinear autonomous systems have been made. These attempts are summarized and evaluated in some detail, as they form the basis for the variable gradient approach proposed in this thesis. It is assumed that the system whose stability is being investigated is represented by …

Two Dimensional Signal Representation Using Prolate Spheroidal Functions, G. R. Cooper, D. A. Landgrebe
Two Dimensional Signal Representation Using Prolate Spheroidal Functions, G. R. Cooper, D. A. Landgrebe
Department of Electrical and Computer Engineering Technical Reports
The most widely used methods of signal representation are the time function and the frequency function or spectrum representations. This work is concerned with the development of a representation which is a combination of these two. Two previous attempts at defining this type of signal representation, which is referred to as two dimensional representation, have been made and a summary and evaluation of these attempts is presented. The primary objective of the work reported here was to develop a practical two dimensional representation which has the desired two dimensional conceptual properties as well as mathematical convenience. The representations defined are …

Department of Electrical and Computer Engineering Technical Reports
This is the second part of a 2 volume report on the specification and data presentation in linear control systems. This volume deals with Sample Data Systems, Linear Time Variable Parameter Systems, and Performance Indices, which are respectively Chapter II, III, and IV of the volume. Since these subjects are somewhat unrelated, a separate abstract is given at the beginning of each chapter, with the exception of the introductory Chapter I. The separate chapter abstracts are repeated here for the convenience of the reader. Abstract - Linear Sampled Data Control Systems The specifications recommended, for use with sampled data control …
Stability Of Nonlinear Control Systems By The Second Method Of Liapunov, John E. Gibson, Eccles S. Mcvey, C. D. Leedham, Rekasius Z. V., Schultz D. G., Sridhar R.
Stability Of Nonlinear Control Systems By The Second Method Of Liapunov, John E. Gibson, Eccles S. Mcvey, C. D. Leedham, Rekasius Z. V., Schultz D. G., Sridhar R.
Department of Electrical and Computer Engineering Technical Reports
This report investigates the stability of autonomous closed-loop control systems containing nonlinear elements. An n-th order nonlinear autonomous system is described by a set of n first order differential equations of the type dxi/dt=xi(x1, x2, …xn) i=1,2,…n. Liapunov's second (direct) method is used in the stability analysis of such systems. This method enables one to prove that a system is stable (or unstable) if a function V=V (x1, x2, … xn) can be found which, together with its time derivative, satisfies the requirements of Liapunov's stability (or instability) theorems. At the present time, there are no generally applicable straight forward …
