New trends in fibre optic sommunications
Lubajo, Lubajo Moses Wolyan ; Dejdar, Petr (oponent) ; Münster, Petr (vedoucí práce)
Optical fiber transmission is one of the leading methods of information transfer for long distance transmission. Various modulation formats have been developed to maximize information transferred through a communication channel. Such formats range from those that transfer one bit per symbol (such as Binary Phase Shift Keying, BPSK), or Quadrature Phase Shift Keying, 3 bits such as in 4 bits per symbol such as Dual Polarization Quadrature Phase Shift Keying and many other modulations. The goal of this thesis is to create and implement a 100 Gbps transmission system using DP QPSK modulation format. The results are discussed with respect to what was successfully implemented and improvements that can still be made to enhance the transmission distance and reduce BER among others. The simulation software used is PHOTOSS.

Implementation of the NB-IoT and LTE-M Technologies within the NS-3 Simulation Tool
Lubajo, Lubajo Moses Wolyan ; Zeman, Kryštof (oponent) ; Mašek, Pavel (vedoucí práce)
The Low Power Wide Area Network (LPWAN) consists of a number of wireless communication technologies that compete in the Machine Type Communication (MTC) space: Narrow Band Internet of Things (NB-IoT), Long Range (LoRaWAN) and Sigfox. Each has its own drawbacks and strengths. This bachelor thesis focused on the NB-IoT technology. It operates in licensed shared spectrum and offers increased link budget as well as extended coverage. The goal of this bachelor thesis is to create and implement an NB-IoT scenario in NS-3 Simulator. The results are discussed with respect to what was successfully implemented and improvements that still need to be made for comprehensive implementation of NB-IoT in the NS-3 Simulator.
