MVE135 Random Processes with Applications, 7.5 credit points, 2007/2008Aim The purpose of the course is to provide the students with the theoretical framework fundamental to the processing of signals with random variation. Starting from basic probability the course proceeds to a thorough study of models for stochastic processes which are relevant in processing of random signals, and gives techniques for manipulating and study of these signals. Practical methods for random signal analysis and filtering are also included. The level should be such that the student should be able to take an active part in designing and optimizing engineering systems involving random signals.Learning outcomes After completion of the course the students should be able to - define and explain fundamental probability tools used in the design and analysis of communication systems, with emphases on multidimensional joint distributions, the Gaussian one in particular, conditional expectation and conditional variance, convergence of random variables and limit theorems for sums of independent and identically distributed random variables -describe the basic statistical principles involved in point and interval parameter estimation as well as in hypotheses testing - identify basic models of random processes and explain their use for the designing of components in communication systems and analysis of their effect on system performance. These models include the Poisson process, Markov processes, Gaussian processes, white noise, and stationary stochastic processes - use wide-sense stationary processes for modeling systems involving random signals and noise. In particular the students should have got a firm grasp on the important class of ARMA processes - estimate second-order characteristics from data, including non-parametric estimation of the power spectral density, and understand the statistical properties of these estimates - explain the mathematical techniques for design of optimal linear systems for signal processing, with emphasis on match filtering and the Wiener filter. Organization The course comprises lectures, classes with exercises and discussions, computer laborations, and home assignments. Course Book Scott L. Miller, Donald G.
