Projects:

GA19-22248S - Deterministické, chaotické a stochastické jevy v sub-mikronových integrovaných strukturách
ED2.1.00/03.0072 - Centrum senzorických, informačních a komunikačních systémů (SIX) Výzkum a Vývoj pro Inovace.

Program allows numerical analysis including graphical visualization of solution associated with both mathematical and circuit model of the multi-state memory cell having piecewise linear resistors. Derived differential equations for this functional block represent third-order autonomous deterministic dynamical system. Script proves that robust chaotic attractor is belongs to one possible solution for both binary and ternary memory. Also, software performs transformation of state matrices for individual segments of vector field into Jordan form.

Projects:

LTC18021 - Budoucí bezdrátové a radiové komunikační sítě v reálných podmínkách (FEWERCON)

FEKT-S-17-4426 - Komunikační systémy budoucí generace

The IEEE 802.11ad SC-PHY Simulator is a simulation tool to provide reproducible evaluation of the IEEE 802.11ad single carrier (SC) baseband signal on the physical (PHY) layer level. It allows a flexible set of the most important system parameters, including code rate of the channel encoder and type of modulation. Furthermore, it is possible to select among three channel models: AWGN, fading channel with user defined settings and 60GHz indoor channel model. There is a unique option to select a 60 GHz indoor channel model which is based on real measurements realized in an indoor office at Department of Radio Electronics (DREL). Bit and Frame Error Ratio (BER and FER), data throughput and 60GHz channel characteristics in the time domain are the most important parameters used for the evaluation of the simulation results. The IEEE 802.11ad SC-PHY Simulator has been developed in the program environment MATLAB (version 2017b) which, including the raw data of the measured 60GHz channel, can be downloaded here. More information about this simulator can be found on the linked webpages.

VFTool is a software for the approximation of complex functions in the frequency domain. VFTool is a standalone MATLAB toolbox having its own GUI (Graphical User Interface). The reference (measured) curve can be either loaded (using file formats *.txt or *.xls), specified using complex residues and poles or defined using a complex handle function. The resulting VF (Vector Fitting) model can be obtained in two ways: 1) automatic - the model order and VF settings is given by the toolbox automatically, or 2) user-defined ? the model order and VF settings fully specified by the user. The VF model can be exported to file formats *.mat, *.xlsx a *.txt. The toolbox can be downloaded here.
