  17. Geo-statistical Methods for Estimating Channel Parameters in Vehicular Scenarios

    The spatiotemporal behavior of radio-frequency channels can be estimated by various geo-statistical methods. Channel measurements are usually available only at a few positions, e.g., at the positions of certain base stations. Geo-statistical methods can then be used to interpolate between the known data and estimate the channel parameters at desired positions, e.g., at the positions of mobile users. The aim of this Ph.D. thesis is to devise suitable methods for estimating channel parameters, such as RSSI or other channel quality indicators, in the case of moving terminals. We are especially interested in vehicular scenarios where also certain mobile users provide channel quality measurements. The devised methods should be able to exploit the repeated measurements of static base stations and mobile users for a reliable spatial interpolation and temporal prediction of channel quality indicators for other mobile users.

  18. Channel models for future generations of mobile networks

    Steadily growing number of communication devices per area and increasing quality of services require allocation of more frequency resources.

Specific limitations of MMW signal propagation, extremely large bandwidth and time variable environment caused by mobile users connected to a backhaul networks traveling in rugged municipal environments create unprecedented challenges to the development of broadband communication systems using advanced technologies for eliminating the undesirable time varying channel features. The aim of the project is measurement and modelling of the broadband non-stationary MMW channels in time and spatial domain (i.e. modelling the environment between mobile users and backhaul) in order to evaluate feasibility of advanced techniques such as beamforming or massive MIMO spatial multiplexing implementation.

  31. PAPR reduction for 5G signals

    The problem of power efficiency is one of the drawbacks of current as well as future mobile communication systems. One of the main sources of low power efficiency is high ratio between Peak and Average Power (PAPR) of communication signals. Traditional signal processing methods for PAPR reduction were designed for OFDM systems and their direct application to forthcoming signals planned for 5G are not possible, e.g. due to the worse time localisation of symbols, where several symbols can overlap in time. The aim of the topic is to propose new approaches to PAPR reduction applicable these post-OFDM 5G waveforms.

Accordingly, the research in the thesis will deal with the analysis of pulsed EM wave field propagation in the close vicinity of (a simplified model of) a human body. The validity of the proposed closed-form propagation models will be demonstrated by means of both numerical and real-life experiments.

    Tutor: Štumpf Martin, doc. Ing., Ph.D.
  36. Receiving of very weak radiofrequency signals

    Reception of microwave signals coming from the universe is characterized by very low Eb/N0 ratio. That is mostly concerned with phase or frequency shift keying of a carrier or sub-carrier. Reduced bandwidth is applied for AWGN elimination as the signal’s source increases. For this reason very high frequency stability has to be achieved by locking to an atomic frequency standard as well as precise compensation of Doppler shift. Basic requirement is a low value of equivalent system’s noise temperature achievement, related to optimized radiated pattern of the parabolic reflector feed. A part of the project is also methodology of the system sensitivity measurement by means of extraterrestrial noise sources.

The described research is a part of a prepared project to be solved in cooperation with the Center of Mental Health in Prague and Nencki Institute of experimental biology in Warsaw.

    Tutor: Raida Zbyněk, prof. Dr. Ing.
  38. Sensor networks for vehicles
