Coexistence of DVB-T2 and LTE in the 800 MHz band
Walach, Dominik ; Miloš, Jiří (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with the study and evaluation of coexistence scenarios which can occur between DVB-T2 and LTE systems in the UHF band 800 MHz Both DVB-T2 and LTE systems are briefly described, and their common frequency bands are defined. An appropriate laboratory workplace is proposed and realized for the measurement, analysis and evaluation of the DVB-T2 and LTE coexistence scenarios. These systems work in adjacent or even in the same frequency bands. Thereby these systems can coexist, and different coexistence scenarios can occur.

Estimating mobile coverage by means of regression
Walach, Dominik ; Raida, Václav (referee) ; Blumenstein, Jiří (advisor)
This diploma thesis deals with the use of freely available data sets to estimate the signal strength in localities where measurements are missing. This work aimed to use interpolation and regression methods to estimate as accurately as possible the possible signal coverage in a given locality. First, data sets were analyzed, based on results, a test model for various methods has been created. The methods with the best results have been implemented on real data sets containing thousands of measurements. At the end of the work, accurate estimates are commented and circumstances to reduce the deviation of the measured and calculated values are specified.

Coexistence Between Dvb-T2 And Lte Systems In The 800 Mhz Band – A Measurement Methodology
Walach, Dominik
This article deals with the study of coexistence between DVB-T2 and LTE systems. Coexistence scenario between DVB-T2 and LTE systems in the 800 MHz UHF band is defined. Next, a laboratory workplace is realized, and a measurement methodology is proposed. Its functionality is verified by experimental measurements. The proposed concept also facilitates to test sensitivity of DVB-T2 receivers (set-top-boxes) against interfering LTE signals.
