Time-varying K factor of the mm-Wave Vehicular Channel: Velocity, Vibrations and the Road Quality Influence
(IEEE, 2017-10-07)Abstract—This paper evaluates real-world intra-vehicle millimeter-wave (mmWave) channel measurements performed in a vehicular environment. Utilizing a correlative time-domain channel sounder, we demonstrate the dependency ... -
TISO Adjustable Filter with Controllable Controlled-Gain Voltage Differencing Current Conveyor
(Faculty of Electrical Engineering and Information Technology, Slovak University of Technology, 2014-06-02)The main aim of this paper is to present solution of triple-input single-output (TISO) filter with independently adjustable pole frequency, quality factor, bandwidth and also gain. Filter is universal, operates in current ... -
Tunable Fractional-Order Capacitance Multiplier Using Current Gain Adjustment
(IEEE, 2020-11-25)This paper brings new solution of linearly adjustable fractional-order capacitance multiplier. The adjustable current gain, linear in wide range of input current and with linear dependence on driving voltage, serves for ... -

Voltage Gain-Controlled Third-Generation Current Conveyor and its All-Pass Filter Verification
(IEEE, 2017-09-04)The paper presents a new active building block (ABB) called minus-type voltage gain-controlled third-generation current conveyor (VGC-CCIII) in which the voltage gain between Y to X terminal can be controlled. The usefulness ... -
Wavelet Co-movement Significance Testing with Respect to Gaussian White Noise Background
(Helenic Military Academy, 2018-01-09)The paper deals with significance testing of time series co-movement measured via time-frequency approach. We use the wavelet analysis for estimation of the co/cross-spectra for the co-movement analysis. This technique is ... -
Wideband UHF and SHF long-range channel characterization
(Springer Open, 2019-07-23)This paper presents an outdoor long-range (from 315 m up to 5.3 km) fixed channel campaign for both ultra high frequency and super high frequency bands with co-polarized horizontal and vertical antenna configurations. It ...
