Abstract : The purpose of this project was to design a tutorial aid for the study of signal detection theory and its application to communication receiver design. An interactive computer program was developed to solve problems concerning the detection of amplitude and/or phase shift keyed signals in the presence of additive white gaussian noise. The probability of error criterion was used to compare and optimize signal set parameters. The user may input from 2 to 33 twodimensional signal vectors ranging in amplitude from 10 to the 6th power to 10 to the 4th power units, specify signal probabilities, and system noise energy. The computed system and signal statistics include signal energy, signaltonoise ratio, Union Bound on and integrated values of probability of error, noise power spectral density, and center of gravity. Graphical displays provide signal set with coordinates and decision region boundaries. Modifications to signal set may be performed via translation, rotation, or scaling, and deletion or addition of signals. The programming language used was FORTRAN 77 with graphical capability provided thru the Tektronix PLOT10 graphics package. The program (less graphical capability) may be executed from any interactive terminal supported by the FORTRAN 77 compiler and the 'International Mathematical and Statistical Libraries' (IMSL) routines MDNOR and MDBNOR. For graphical displays, use of Tektronix terminals model 4014, 4012, or 4010 is required. (Author)
