Analysis of Coexistence of DRM Plus and FM Broadcasting Systems
(Společnost pro radioelektronické inženýrství, 2015-12)
This paper deals with DRM (Digital Radio Mondiale) Plus and FM (Frequency Modulation) radio broadcasting systems coexistence. It brings results based on measurement of mutual interferences of each to other. Minimal necessary ...
Dopravní nehody a kamery – případová studieTraffic Accidents and Cameras – Case Study
(Akademické nakladatelství CERM, 2018-06)
S rozvojem palubních kamer a zvyšováním podílu sledovaných úseků komunikací se zvětšuje podíl dopravních nehod zaznamenaných na video. Cílem článku je ukázat základní metody, s využitím minimálního množství softwaru, pro ...
Empirical Models for Indoor Propagation in CTU Prague Building
(Společnost pro radioelektronické inženýrství, 2000-04)
Indoor propagation modelling is demanded for the design and maintenance of indoor wireless services. Empirical modelling seems to be the most efficient approach. Even so there are many studies dealing with empirical models ...
Simple Chaotic Oscillator: From Mathematical Model to Practical Experiment
(Společnost pro radioelektronické inženýrství, 2006-04)
This paper shows the circuitry implementation and practical verification of the autonomous nonlinear oscillator. Since it is described by a single third-order differential equation, its state variables can be considered ...
Modeling and Measurement of Image Sensor Characteristics
(Společnost pro radioelektronické inženýrství, 2004-12)
The optical transfer function (OTF), as an objective measure of the quality of optical and electro-optical systems, is closely related to the point spread function (PSF) and other derived characteristics, such as the ...
Laboratory of Digital Video and Television Technology
(Společnost pro radioelektronické inženýrství, 2004-12)
This short paper provides information on the technical instrumentation and application possibilities of the newly installed laboratory of digital video and television technology at the Department of Radio Electronics FEEC ...
Rural Optical-Propagation Measurements
(Společnost pro radioelektronické inženýrství, 2011-04)
Compared with traditional communication technologies like wired or radio frequency communications, optical wireless communication has a unique fading behavior of the received signal, that does not allow to use existing ...
Current-Mode Dual-Phase Precision Full-Wave Rectifier Using Current-Mode Two-Cell Winner-Takes-All (WTA) Circuit
(Společnost pro radioelektronické inženýrství, 2011-06)
In addition to the recently proposed full-wave rectifier by Prommee et al. using voltage-mode (VM)two-cell winner-takes-all (WTA) circuit, we present current-mode (CM) precision full-wave rectifier using CM two-cell WTA ...
Maximum Available Accuracy of FM-CW Radars
(Společnost pro radioelektronické inženýrství, 2009-12)
This article deals with the principles and above all with the maximum available measuring accuracy analyse of FM-CW (Frequency Modulated Continuous Wave) radars, which are usually employed for distance and velocity ...
Co-channel and Adjacent Channel Interference Measurement of UMTS and GSM/EDGE Systems in 900 MHz Radio Band
(Společnost pro radioelektronické inženýrství, 2008-09)
This paper is concerned with inter-system and intra-system interference measurements of 2.5G and 3G mobile communication systems. The both systems UMTS and GSM/EDGE are assumed to operate in a common radio band of 900 MHz. ...
