Cooperation of telecommunication and information transmission systems
Novák, Daniel ; Vychodil, Petr (referee) ; Škorpil, Vladislav (advisor)
Some telecommunication systems are theoretically analyzed in this thesis. Basic types of digital modulations are also analyzed here and applying them to practice. In the implementation part of the thesis are realized three laboratory tasks addressing to modulations issue, coding and data transfer in the SONET network. Tasks are simulated by EMONA TutorTIMS. software. In appendix are described functions and parameters of used modules.

Simulation of the MIMO systems
Kančo, Vít ; Vařacha, František (referee) ; Prokopec, Jan (advisor)
MIMO systems are mainly used in application for wireless communication. Their principle is to use a large number of antennas for transmition and the reception of a signal. The core of these systems is to use space-time coding and either block or trellis space-time code. In the future, it is assumed enormous enlargement MIMO systems in many applications

High-speed optical transmission systems
Pekárková, Kateřina ; Číž, Radim (referee) ; Münster, Petr (advisor)
The diploma thesis is focused on high-speed optical connections using optical fibers for transmission and transmission systems with speeds above 100\,Gb/s. In the first part of the work, the theory of the area of optical high-speed connections is discussed, especially the work is focused on the coherent type of data transmissions. Modulation and multiplexing formats, chromatic dispersion, modal and polarization modal dispersion, optical fiber attenuation and nonlinear phenomena are also described. The theoretical part of the work also deals with the description of the differences between coherent and non-coherent transmission methods and the description of coherent high-speed optical transmission and its components. The practical part contains two laboratory tasks that, using simulations in the VPIphotonics environment, compare two-state and multi-state modulation for systems with a transfer rate of 10\,Gbit/s and 100\,Gbit/s. The properties of these modulation formats are demonstrated using decision eye diagrams, constellation diagram and bit error rate values for different lengths of optical fiber, which are the output of the simulation environment.

Lineární adaptivní slepé MMSE detektory DS-CDMA signálů
Šimša, Jan
The contribution concentrates on detection of CDMA signals by linear adaptive blind MMSE detectors. Some rules of adaptation and their parameters are discussed. A limited need of a priori information and their adaptability to changing environment cause these detectors very attractive for applications
