|The subject Advanced methods of signal processing follows the subjects of bachelor study dealing with analog and digital signal processing and system analyses (Signals and systems, Digital signal processing, etc.).
It is designed for students and engineers in electrical engineering, specializing in measurement, regulation, electronics, communication
technology, biomedical engineering, signal processing. The student acquires and extends his / her knowledge and skills in the problems, methods of advanced signal processing methods.
The student will get knowledge of the uniform methodology of description of signal processing methods in the frequency domain using the FFT algorithm, knowledge of signal processing methods such as window signal functions, complex and real cepstral signal analysis, octave signal analysis, signal waveform transformation with multiple resolution signal analysis , signal interpolation and signal decimation, mixer implementation principles, multiplier detector and frequency multipliers, passband filters and narrow band filters.
Students will learn the principles of compression and audio signal processing, compression standards MP3, WMA, ACC, OCG. Noise suppression, effect audio signal processing, compression and image processing principles, compression standards with MPEG video and audio encoding, JPEG compression of digital video signals.
Students will obtain knowledge of digital signal modulations in baseband modulations PAM, PCM, PWM, PPM, PNM. Students will also acquire knowledge of analogue modulations AM, DSB-SC and SSB-SC (LSSB-SC and USSB-SC), analog FM and PM (NBFM, WBFM) modulation, digital modulations OOK, DPSK, FSK, QAM, APSK, OFDM, DAB, DBM, DVB, and FEC security algorithms.
For the study of the subject, There are expected the knowledge of mathematics in the scope of the basic course lectured at VSB-TU Ostrava, FEI, basic knowledge of physics and basic knowledge of electrical engineering. Students will also work with mathematical programs designed for signal processing and analyzing. Students use and learn to work with measuring devices in laboratory.
There is assumed the basic subjects knowledge from the bachelor study. Advanced signal processing methods is subject which covering a wide range of knowledge. Mathematical sentences used always discuss their physical interpretation. For the derivation of sentences and their proofs, some formulas describe the statistical view of the issue, the student refers to the cited literature. For more information, see the Department Cybernetics and biomedical engineering website of the FEI.
