Digital Communications 1

Course title: Digital Communications 1

Code: 3ФЕИТ10З011

Number of credits (ECTS): 6

Weekly number of classes: 3+1+1+0

Prerequisite for enrollment of the subject: None

Course Goals (acquired competencies): The student will acquire fundamental knowledge of the field of digital communications, such as various techniques of conversion of analog signals to digital signals, various types of digital modulation techniques, the optimum receiver and the optimum detector of digital signals and detection error probability, and transmission of digital signals through band-limited systems and equalization techniques. The acquired knowledge is the basis for understanding the modern digital transmission systems, and a prerequisite for other subjects with more specific content.
