Course detail
Implementation of Communication Systems
FEKT-MPA-IKSAcad. year: 2021/2022
The course is oriented to the real implementation problems of radio transmitters and receivers of single- and multi-carrier communication signals. Its emphasis is on both the theoretical description of basic algorithms for communication signals processing (sample rate change, filtration, synchronization, equalization, etc.), as well as on their practical software implementation with the use of available hardware (fixed-point arithmetic, analysis of signal transmitted from front-end, etc.). During the computer laboratories, students will get hands-on experience with the implementation of various transceiver algorithms on real signals of analog (e.g. FM radio) as well as digital (e.g. OFDM according WiFi IEEE 802.11a, FSK, QPSK/QAM) systems.
