Subject description

Prerequisits:

• Enrollment.
• Mathematica 1 to 4.

Content (Syllabus outline):

Basic telecommunications model. Sampling. Bseband transmission (pulse transmission, power spectrum of coded signal, separation direction of transmission, synchronization, optimal receiving filter, intersymbol interference). Adaptive systems (adaptive filters, adaptive algorithms, eequalizer, intersymbol interference canceller). Modulation (amplitude modulation, frequency modulation, phase modulation, quadrature modulation, digital modulation techniques, spectral efficiency, multiple carriers modulation). Transmission channel capacity. Multiple access (random multiple access, frequency division multiple access, time division multiple access, spread spectrum and code division multiple access, cellular networks). Coding (linear block codes, convolution codes, trellis codes, product codes). Decoding (soft and hard decision, detection and error correction, maximum likelihood and forward error correction, Viterbi algorithm).

Objectives and competences:

• Learning about basic principles of signal transmission in digital communications.
• Learning about the problems that occur with data transmission via non-ideal channel, which introduces distortion and noise, and procedures to address them.
• Learning about different ways to share a common transmission medium primarily in wireless communications, where the capacity is a common medium is limited, because we all users share the same medium.

Intended learning outcomes:

Knowledge and understanding of the basic principles of digital transmission, errors caused by interference, and procedures for error correction and efficient use of the frequency space.

Learning and teaching methods:

Lectures on which the student is acquainted with the theoretical basics and lab work, where he learns how to solve some practical problems in the spirit of teamwork.
