4.                  The fundamentals of channel coding systems; interleaving, randomization, concatenated coders, iterative (turbo) coders.

 

5.                  Digital modulation schemes (MPSK, MFSK, MQAM); waveforms, vector representation, bandwidth, transmit power, symbol error rate, transmitter and receiver structures, higher-order digital modulations.

 

6.                  Coded modulation systems: trelis-coded modulation, TC-MPSK, TC-MQAM, soft decoding, continuous phase modulations (CPM)

 

7.                  Properties of transmission media: terrestrial and satellite microwave media, the characteristics of mobile and fixed radio channels (e.g. WSSUS). The properties of broadcasting (terrestrial and satellite) radio channels.

9.                  Multi-channel, multi-carrier systems: OFDM (orthogonality, channel correction in OFDM systems, guard interval, etc.), FBMC; point-to-point and point-to-multi point links also for SISO, SIMO, MISO, MIMO channels.

 

10.              Digital television broadcasting systems (DVB system variants), the design and properties thereof. Complementary services of DVB (RCT, MHP, etc.).

 

11.              The design and properties of digital radio systems (DAB, DAB+, FMeXtra, HD-Radio, DRM, DRM+, as well as ISDB-T/SB mentioned) (channel coding, modulation).

 

12.              Convergence of communications and broadcasting systems: merger of TV and radio standards (T-DMB and radio broadcasts in DVB-ben), integration with communications systems (SDR, LTE, 5G), virtual networks.

 

13.              Analysis of communications and broadcasting systems; investigation of spectral and transfer characteristics, effects of linear and non linear distortions, time and frequency domain characteristics, modulation analysis and bit error rate as well as packet error rate measurements.

 

14.              Presentation of the main elements of wideband wireless systems via examples (mobile and fixed, terrestrial and satellite networks). Baseband presentation of digital transmissions, overview of modeling and simulation procedures. Quality analysis of communications and broadcasting systems, analog signal quality assessment, digital QoS parameters, digital picture quality assessment.

Based on the theoretical background presented in Communications Theory, this subject introduces the fundamental methods applied in wideband wireless communications and broadcasting systems, covering the following main topics.   The first topic covers some special aspects of digital communications, including spectrally efficient coding procedures (higher-order digital modulations ― MQAM, continuous phase modulations ― CPM, multi-carrier methods ― OFDM, FBMC), coded modulation systems, spread spectrum systems (for both constatnt and variable rate services), as well as multiple access systems (CDMA, FDMA, TDMA, SDMA) and multi-user receive techniques.   The second topic introduces the properties of transmission media, giving an overview of the characteristics of terrestrial and satellite microwave media, terrestrial and satellite mobile, fixed and broadcasting radio channels (e.g. WSSUS), also covering point-to-point and point-multi point (e.g. MIMO) systems.   The third topic is the presentation of special systems and devices, including terrestrial and satellite broadcasting and communications systems, such as DAB, DVB and DRM, as well as wideband and fixed wireless access (BFWA) networks, together with the aspects of the convergence of cellular and broadcasting networks (SDR, LTE, 5G, DVB IP, DVB RCT/S/C).   The fouth topic gives an in-depth overview of the measuring technology of state-of-the-art digital broadcasting and communications systems, detailing their time and frequency domain properties, covering also modulation analysis, as well as bit error and packer error rate related issues. The baseband representation, as well as the modeling and simulation of these systems is also introduced, in addition to the generation of real and complex signals with given stochastic parameters along with simulation-based estimation of system parameters.   By the end of the semester, the students will develop skills which enable them to design, model and investigate the fundamental (physical-layer related) properties of the emerging wideband fixed, cellular and broadcasting systems.
