Random Processes in Systems

Course Description

The course gives knowledge of the theory of random processes and applications in the systems for signal processing and analysis. Continuous and discrete random signals. Random processes. Stationarity and independence. Correlation functions and power spectral density. Random process in linear systems. Signal parameters estimation. Detection. System identification using cross correlation. Noise modeling and characterization. Noise factor. Optimum linear systems. Wiener filter. Matched filter. Realization of the optimum systems. Signal extraction from the noise by correlation and using matched filter. Signal quantization. Applications in communication, automation and measurements.

General Competencies

The course provides fundamental knowledge in stochastic systems and statistical signal processing with emphasis on practical engineering applications. The students will be able to model random processes and deeply understand the concepts of stationarity, ergodicity, independence, correlation and power density, as well as noise modeling concepts. They will be able to design an optimum linear system: Wiener filter or matched filter, or to solve a number of problems in communication, automation, and measurements.
