- High-capacity optical transmission systems
Optical transmission systems have evolved rapidly over the last decade to meet the ever-increasing demand for increased capacity. Wavelength multiplexing is now widely used to increase optical fiber capacity, and further capacity increase is achieved by increasing data transfer rate. In order to meet these requirements for future high-capacity transmission systems, several technical challenges need to be addressed, such as new optical modulation formats with high spectral efficiency, optimization of receivers capable of detecting new modulation formats, mitigation of linear and nonlinear phenomena in optical fibers, or amplification signal with minimal noise.

Today's digital world is dependent on data security during communication but also in storage, for example in e-banking, e-commerce, e-health or e-government. With the advent of quantum computers, there is a risk of potential security breaches today. Quantum Key Distribution (QKD) provides a way to distribute and share secret keys that are necessary for cryptographic protocols. The information is coded into individual photons. Integrating QKD systems into existing network infrastructure used for telecommunications is a topical challenge. Some other major challenges include increasing of the key rate, increasing the range of the QKD system, or reducing the complexity and robustness of existing solutions.

- Sequential Estimation of Arterial Wall Contours
Examination of the common carotid artery (CCA) based on ultrasound measurements is an effective method for detecting cardiovascular diseases. In particular, the spatial evolution of the CCA wall is related to diagnostically relevant parameters describing, e.g., CCA tissue elasticity. Accordingly, the goal of this PhD thesis is to estimate the time-varying contour of the CCA wall from an ultrasound video sequence. This is to be achieved by developing a sequential extension of a machine learning method known as Gaussian process regression (GPR). In the GPR method, a function to be learned is represented by a random process, which avoids an explicit parametric representation. The desired sequential extension of the GPR method should be able to continuously track the detailed shape of the CCA wall over a time period of arbitrary duration.

- Smoothing Methods for Arterial Wall Motion Tracking
Examination of the common carotid artery (CCA) from ultrasound measurements is an effective method for detecting cardiovascular diseases. The goal of this PhD thesis is the development of time-recursive methods for tracking CCA- related multiple scatterers in an ultrasound videosequence. These methods will be based on hidden Markov models describing the temporal evolution of the scatterers and smoothing techniques for multitarget tracking, and they will take advantage of the strong statistical dependencies of the scatterers. The smoothing approach is expected to outperform current filtering approaches at the expense of a higher computational complexity.

- Spatial Audio Signal Processing Using Small-Size Microphone Arrays
Microphone arrays of small dimensions, mainly fitted with MEMS microphones, are currently used in a number of applications, such as voice assistants, robots or monitoring in sensor networks, especially for their ability of spatial filtering of the sound signal from background noise. However, they also have potential in multimedia applications including augmented and virtual reality. The problem, however, is the limitation of their dimensions with respect to the spatial filtering capability at low sampling frequencies. The aim of this dissertation is to use new methods of spatial filtering of sound signal picked up by a field of microphones in order to further reduce the dimensions of the field and increase the resolution and accuracy of filtering. The dissertation will focus not only on the research for suitable algorithms of signal processing, but also on its mechanical design enabling the adjustment of acoustic properties of microphones, especially the shaping of directional characteristics. The research will be carried out in cooperation with the Faculty of Transportation Sciences of the Czech Technical University and the Université du Maine Le Mans.
- Using Machine Learning for Modelling of Audio Systems
Neural networks and machine learning are currently used in the area of audio signal processing for data mining, e.g. recognition of genre, music information retrieval from recordings, etc., and speech processing, such as word recognition, speaker identification, emotion recognition, etc. However, their potential use is also in modelling of audio systems. The aim of dissertation thesis is to find algorithms for optimization of parameters of digital musical effects, algorithms for room acoustic simulation and more using machine learning and hearing models for training of neural networks. The research will focus on the static optimization of the system parameters according to the original analog system and on the dynamic change of the parameters in real time on the basis of the properties of the processed audio signal. Research will be conducted in collaboration with companies dealing with the development of software for processing audio signals.

- Novel distributed and quasi-distributed fiber optic sensing systems
The work focuses on the design, simulation and development of distributed and quasi-distributed fiber optic sensing systems. These systems use conventional single-mode telecommunication optical fibers, multimode fibers, polymer optical fibers (POF), microstructural fibers, multicore fibers, or other special fibers as a sensor. Using scattering phenomena (Raman, Brillouin, or Rayleigh scattering), or possibly changing the parameters of the transmitted optical signal (change in intensity, phase, polarization, etc.), it is possible to obtain information about temperature, vibration and other physical quantities along the optical fiber.
- Optical fiber amplifiers
The ongoing growth of telecommunications networks is currently made possible by optical fibers. Together with telecommunications systems, optical amplifiers have made it possible to transmit huge amounts of data from kilometers distances to transoceanic distances, providing the capacity needed for current and future communications networks. Optical amplifiers play an important role not only in optical telecommunications, but also in optical sensing and many other applications. Rare-doped amplifiers (eg Erbium-doped fiber amplifiers), Raman amplifiers, and semiconductor optical amplifiers (SOA) are common today. Special types of amplifiers such as parametric amplifiers offer many advantages, but they are complex and expensive. In addition to the amplifiers themselves, new types of optical fibers (eg multicore) and the possibilities of amplification in these fibers have to be considered.
