Mikrohullámú reflexiómérés hibájának csökkentése minimális érzékenységű kalibráció alkalmazásával
(1993-08-09)
Explicit kifejezést adunk a hibakorrekció utáni reflexiós tényezőnek a kalibráló elemek reflexiós tényezőire vontakozó érzékenységeire és megmutatjuk összefüggésük invarianciáját. Az érzékenységek összegének állandósága ...
Optical Processing and Transmission of Subcarrier Multiplexed Microwave Signals
(1999-10-04)
The subcarrier transmission of microwave signals is a perspective method for the optical fiber links. Several approaches are presented covering the generation and reception of the subcarrier optical signals. The transmission ...
Radio-frequency Interference in Radio-over-Fiber Distribution Networks
(1999-03-21)
Radio-over-fiber distribution networks have been investigated by several authors recently [1-4]. The different proposed solutions combat the difficulties arising in the optical part of the network such as chromatic dispersion ...
General Approach to Chromatic Dispersion Analysis of Microwave Optical Link Architectures
(1999-10-12)
Fiber-optical transmission of microwave (MW) and millimeter-wave (MMW) signals in the λ=1.55 μm wavelength window has become an intensive research area of MW photonics recently [1]. A main field of potential applications ...
Spectral Stability of Radio Transmitters in Point-to-Multipoint Access Systems
(1999-03-21)
Stability of microwave (MW) transmitters is discussed in the paper. Similarly to existing definitions of frequency and output power stability [1], we introduce spectral stability. To characterize spectral stability of radio ...
Optical Generation of Millimeter Waves for Mobile Radio Systems
(1999-03-21)
A new approach is presented for the optical generation of millimetre waves with the intention to feed the base stations of mobile radio systems. In this approach an optically transmitted subharmonic reference signal is ...
QAM Radio Reception in Presence of Interference and Noise
(1999-10-13)
Transmission and reception of digitally modulated microwave (MW) and millimeter-wave (MMW) radio signals are widely investigated [1,2,3,4]. This paper addresses the problem of digital MW/MMW radio reception and demodulation ...
Capacity Expansion and Modernization of Core Network Elements Running on ATCA Platform
(2020-04-20)
Actual telecommunications research topics are focusing on cloud-based Virtual Network Functions (VNFs). Less attention is given to the capacity expansion and optimization of existing Physical Network Functions. However, ...
