Lecture 1: Entropy and mutual information

4.1 Non-negativity of mutual information In this section we will show that I(X;Y) ≥ 0, (27) and this is true for both the discrete and continuous cases. Before we get to the proof, we have to introduce some preliminary concepts like Jensen’s in-equality and the relative entropy.

Gaussian processes - Stanford University

processes are the extension of multivariate Gaussians to infinite-sized collections of real-valued variables. In particular, this extension will allow us to think of Gaussian processes as distributions not justover random vectors but infact distributions over random functions.7 3.1 Probability distributions over functions with finite domains

Such signals play a central role in signal and system design and analysis, and throughout the remainder of this text.

Chapter 9 Random Processes - Concordia University

Definition of a Random Process Assume the we have a random experiment with outcomes w belonging to the sample set S.To each w ∈ S, we assign a time function X(t,w), t ∈ I, where I is a time index set: discrete or continuous. X(t,w) is called a random process. If w is fixed, X(t,w) is a deterministic time function, and is called a realization, a sample path, or a

Y. S. Han Random Processes 1 Definition of a Random Process • Random experiment with sample space S. • To every outcome ζ ∈ S, we assign a function of time according to some rule: X(t,ζ) t ∈ I. • For fixed ζ, the graph of the function X(t,ζ) versus t is a sample function of the random process.

Gaussian Random Variables and Processes

Gaussian Random Process Definition A random process fX(t) : t 2Tgis Gaussian if its samples X(t1);:::;X(tn) are jointly Gaussian for any n 2N. Properties The mean and autocorrelation functions completely characterize a Gaussian random process. Gaussian WSS processes are stationary. If the input to an LTI system is a Gaussian RP, the output is
