    This paper treats the detection of pulsed signals in the presence of receiver noise for the case of randomly fluctuating signal strength. The system considered consists of a predetection stage, a square law envelope detector, and a linear postdetection integrator. The main problem is the calculation of the probability density function of the output of the postdetection integrator. The analysis is ... View full abstract»

    Given a set of equally spaced measurements, it is possible to curve fit a "least squares" polynomial to the N observed data points and obtain estimates of the past, present, or future values of the data or its derivatives by appropriate manipulations of the curve fit. This curve fitting can be accomplished by a linear weighting of the observed data over an inte... View full abstract»

    A new kind of random process, the locally stationary random process, is defined, which includes the stationary random process as a special case. Numerous examples of locally stationary random processes are exhibited. By the generalized spectral density \Psi (\omega , \omega \prime ) of a random process is meant the two-dimensional Fourier transform of the cov... View full abstract»

    In many of the applications of probability theory to problems of estimation and detection of random functions an eigenvalue integral equation of the type begin{equation} phi(x) = lambda int_0^T K(x - y)phi(y) dy, qquad 0 leq x leq T, end{equation} is encountered where K(x) represents the covariance function of a continuous stationary second-order process poss...

    The correlation function of "smoothly" limited Gaussian noise is calculated and compared with the correlation function of "extremely" clipped Gaussian noise. The limiting function is assumed to have the shape of the error integral carve. The output spectrum is calculated for the case of noise passed through an RC filter. View full abstract»

    In this paper we wish to show that the fundamental problem of determining the utility of a communication channel in conveying information can be interpreted as a problem within the framework of multistage decision processes of stochastic type, and as such may be treated by means of the theory of dynamic programming. We shall begin by formulating some aspects of the general problem in terms of mult... View full abstract»

    The paper presents a brief exposition of the technique of complex normal random variables as utilized in the study of the envelopes of Gaussian noise processes. The central concept is the pre-envelope z( ) of a real normal process. The pre-envelope z( ) of a real function x( ) is a ... View full abstract»
