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.
