The aim of the course is to increase the understanding of the basic principles and results in the theory of stationary stochastic processes and to add to the arsenal of useful tools for their application. The course givea increased knowledge and skills in stationary stochastic processes on top of basic courses in the subject in the engineering programs: to present and train how stationary process models are constructed and how their mathematical, probabilistic, and statistical properties can be analysed. It is intended as a "second course" in stationary processes; some previous knowledge from mathematical statistics or signal processing helps.

1. How to define a stochastic process; sample space, ensemble, distribution
2. Analytic properties of sample functions
3. Covariance function and its spectral representation
4. Spectral representation of a stationary process
5. Linear filters and their spectral properties, white noise
6. Hilbert transform, envelope, Karhunen-Loève expansion
7. Classical ergodic theory, mixing conditions
8. Multivariate processes and cross-correlation properties
9. Spectral properties of random fields
10. Level crossings, extremes and excursions

Know and understand: how to define a stochastic process from finite-dimensional distributions, conditions for different analytical properties, relation between covariance function and spectrum, sprectral representation of a stationary process and its role in linear filters, sampling of stationary process, envelope, statistical formulations of ergodicity, models for random fields, Rice formula

Relate covariance function to spectrum and find continuity and differentiability properties from covariance and spectrum; use the spectral representation of the process to derive filter properties and other relations; use Rice's formula to evaluate extremal- and crossings properties

Find suitable process models for specific scientific and engineering applications; understand limitations of stationary models; interpret high frequency and low frequency parts of a spectrum in terms of smoothness and long range dependence
