Techniques for the modeling of analog and digital communication systems fall into two classes. Those based on component aspect, those based on system aspect. An approach of these techniques applied to optical fiber link ...

A new approach for the design and construction of low noise broadband optical receivers is presented utilizing distributed amplification based on hybrid integrated technology. Using extremely low noise PHEMTs as well as ...

Optical generation and distribution of millimeter waves have become an intensive research topic recently [1,2]. A main field of possible applications is the millimeter-wave (MMW) wireless distribution of broadband data in ...

The gain-bandwidth relations of distributed amplifiers (DA) are analyzed. It is shown that the amplifier performance is uniquely related to the properties of the active elements and the electrical length of the transmission ...

We present a new technique for remote upconversion by inserting a passive all-optical device in the microwave (MW) fiber-optic link. Using a semiconductor laser directly modulated by two MW signals and an unbalanced ...

Explicit formulas for the sensitivities of the error corrected reflection coefficient (RC) with respect to the RCs of the calibrating elements, and the invariance of their sum are presented. Under the condition that the ...

Optical transmission of microwave (MW) and millimeter-wave (MMW) signals have become an intensive research area in the last decade. There is a growing interest in optical processing of MW signals [1, 2], phased array ...

Density of microwave and millimeter-wave radio relay networks increased with unexpected speed in the last decade. For long time rain attenuation and thermal noise limitation were in the main focus of fixed radiolink design. ...

Deployment of new radio access technology offers the possibility to optimize the existing mobile backhaul. Both the new technology (5G, LTE-A) and the legacy systems (LTE, HSPA, 3G, 2G) utilize the transmission and transport ...

Reliability and availability considerations are discussed in this paper with special focus on ‘cloud based’ Mobile Switching and Application Servers (MSS and AS). Before the extensive deployment of cloud based telecom ...
