Estimation Of Time-Varying Correlation Functions, G. R. Cooper, Helmut Berndt
Estimation Of Time-Varying Correlation Functions, G. R. Cooper, Helmut Berndt
Department of Electrical and Computer Engineering Technical Reports
The need for estimating the auto- or crosscorrelation functions of nonstationary random processes frequently arises in communication and self-adaptive systems. In most situations only one sample function can he observed over finite time. It is the purpose of this work to establish a firm theoretical basis for such a measurement of time-varying correlation functions, and the emphasis here is on suitable estimation procedures rather than specific measurement techniques. Second order stochastic processes are used as a mathematical model. The minimum mean square error between a weighted time average and the true (ensemble average) correlation function is investigated. This procedure leads …

Department of Electrical and Computer Engineering Technical Reports
Under this contract a number of topics have been studied and analyzed in detail in order to bring together and somewhat extend the concepts of communication theory as they apply to some current problems in digital communication systems. Radio wave channels are characterized by a model' which accounts for both multiplicative and additive disturbances, A large amount of experimental data pertaining to radio disturbances is evaluated and correlated. She. importance of the Rayleigh fading channel is emphasized and previous work is extended to determine the capacity and efficiency of the Rayleigh, channel. Detection theory concepts have been extended to treat …

An Analysis Of Traffic Accidents On County Roads, D. F. Petty, H. L. Michael
Indiana Local Technical Assistance Program (LTAP) Publications
The purpose of this research was to investigate the causes of and determine possible remedies for the rising number of county road accidents in Indiana. County road accidents were defined for the purpose of this study as all traffic accidents occurring on roads which are administered by the County Commissioners in Indiana except accidents occurring at intersections of county roads with state highways. These latter accidents are normally charged to state highways. The information used in this research was obtained from accident records. The best available source of this type of information, the accident reports which are filed at the …

Analysis And Design Of Digital Control Systems, K. S. Fu, Raymond M. Kline
Analysis And Design Of Digital Control Systems, K. S. Fu, Raymond M. Kline
Department of Electrical and Computer Engineering Technical Reports
All digital control systems contain at least one signal which is sampled in time and quantized in amplitude. Design of these systems is often based on the assumption that a very large number of levels of quantization is available leading to the approximation of the basically nonlinear system by a linear one. If the actual system is constructed so that the linear assumption is satisfied, the performance may be excellent but other design factors such as reliability, cost, weight, and power consumption may be very unsatisfactory. On the other hand, if the actual system is constructed so that only a …
Inexpensive Digital-To-Analog Converter For Curve Plotting With Small Digital Computers, G. W. Hughes, W. J. Eccles
Inexpensive Digital-To-Analog Converter For Curve Plotting With Small Digital Computers, G. W. Hughes, W. J. Eccles
Department of Electrical and Computer Engineering Technical Reports
The use of the digital computer in engineering schools, with its ability to produce huge tables of results, soon causes the user to wonder if these results cannot be reduced to graphical form automatically. The equipment described here takes the numerical output of a digital computer on punched paper tape, converts the information on the tape to analog voltages, and uses these voltages to plot a point either on a common camera-equipped oscilloscope or on an available plotting table. Since the converter makes use of existing display equipment which every school has, uses low-cost relays, and works at a low …

Correlation Receivers Minimizing Intersymbol Interference, J. C. Hancock, J. M. Aein
Department of Electrical and Computer Engineering Technical Reports
The problem considered here is that of binary pulse communication operating in a white noise environment -wherein interfering signal pulses are generated by any of the following causes t (1) A signaling rate larger than channel bandwidths, causing pulse spill over into succeeding bands. (2) Go-channel interference or cross talk on carrier systems. (3) Signal echoes or reflections due to antenna location or mismatch of high frequency components. The optimum correlation receiver is found to be a linear combination of the desired signal pulse plus the interfering pulse. In severe cases significant improvement can be had over a correlation receiver …
