High bit rate LTE mobile system
Ohera, Vlastimil ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
Aim of thesis was to acquaint with architecture and process of signal in systems using broadband LTE wireless technology. Thesis in detail is described physical layer of system. Next there is described comparison of LTE and WiMAX and table with all present systems. Thesis also is contained information about tested LTE system in real traffic. Next aim was created simulation of LTE system in downlink and uplink. Interface was created for easier configuration of each characteristics of transfer and type of interference of useful signal. This interface is contained control of whole simulation and presentation of measured values. Measured data were processed into graphs, which show dependence of error rate BER on C/N of useful and interference signal.

E-UTRAN Air Interface Description
Opletal, Prokop ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
The aim of this bachelor’s thesis was to study a basic principles of wireless system LTE with a view to radio interface. Readers are familiarize with a basic concepts of system within a text, like modulation OFDM, which is principal for LTE technology. Further in text are shortly describe OFDMA and SC-FDMA technologies, which are employ in LTE downlink and uplink. There are also summarize parameters, which radically change a bit rate in LTE systems. In dependence on the theoretic knowledge was designed a model of LTE system in MATLAB. With this model were performed simulations of transmission of LTE signal through the radio channel.

WiMAX Physical Layer
Víteček, Petr ; Prokopec, Jan (referee) ; Miloš, Jiří (advisor)
This thesis deals with 4G communication system WiMAX and his model of physical layer in MATLAB in uplink direction. In individual parts of this thesis we will have closer look on WiMAX, multiple access scheme OFDMA and OFDM modulation. Further, the physical layer signal processing and as last the model of physical layer in MATLAB. Result of this thesis should be model of physical layer , which will be together with model of radio environment used to calculate graphs of BER depending on S/N ratio. The model should show how is BER affected by different parts of model such as used modulation, code rate of FEC code and used type of interleaving.
