Aim
The student shall aquire a toolbox containing concepts and
models for description and handling of stationary stochastic
processes within many different areas, such as, signal processing,
automatic control, information theory, economics, biology,
chemistry, and medicine. The mathematical and statistical elements
are therefore illustrated using a wide variety of examples from
different areas of application.
The course shall also give the student the ability to identify
the presence of stationary processes in other courses in the
education, use the knowledge of stationary processes in other
courses, and translate the concepts and tools between different
courses, building on stationary processes.
Learning outcomes
Knowledge and understanding
For a passing grade the student must
- be able to perform calculations using expectations, variance,
covariance, and cross-covariance within and between different
stationary processes,
- be able to calculate the relationship between covariance
properties in the timedomain and spectral properties in the
frequency domain for one and several processes,
- be able to formulate linear filters using covariance and
spectral properties,
- be able to estimate covariance function, spectrum, and other
parameters in stationary processes using data.
Competences and skills
For a passing grade the student must
- be able to identify natural situations where a stationary
process is a suitable mathematical model, e.g., within at least one
engineering, science, or economics application,
- be able to formulate a stationary stochastic process model
using a concrete problem within the chosen application,
- be able to suggest model parameters, with the help of
data,
- be able to interpret the model and translate model concepts to
a conclusion regarding the original problem.
Judgement and approach
For a passing grade the student must
- be able to read and interpret technical literature with
elements of stationary processes within the chosen
application,
- be able to describe the model structure and the
conclusions,
- be able to describe the possibilities and limitations of
stochastic models.
Contents
- Models for stochastic dependence.
- Concepts of description of stationary stochastic processes in
the time domain: expectation, covariance, and cross-covariance
functions.
- Concepts of description of stationary stochastic processes in
the frequency domain: effect spectrum, cross spectrum.

noise, Gaussian fields in time and space.
- Stochastic processes in linear filters: relationships between
in- and out-signals, auto regression and moving average (AR, MA,
ARMA), derivation and integration of stochastic processes.
- The basics in statistical signal processing: estimation of
expectations, covariance function, and spectrum.
