Annotation
The course gives an overview of the basic principles and methods used in digital communications in a variety of transmission environments (radio systems, metallic telecommunication lines, optical fiber). The students will learn the basic functional blocks of the communication systems, encoding and decoding, modulation and demodulation methods. The students obtain the idea about sources of errors in the transmission and ways for their detection and correction. They will learn how to calculate the theoretical and practical communication channel capacity, the basic parameters on digital interfaces measurement, including error rate and jitter.
Study targets
Students will learn basic methods of encoding and decoding, modulation and demodulation. Learn to calculate the theoretical and practical communication channel capacity, measuring the basic parameters of the digital interfaces.
