Relaying techniques, in which a source node communicates to a destination node
with the help of a relay, have been proposed as a cost-effective solution to address
the increasing demand for high data rates and reliable services over the air. As
such, it is crucial to design relay systems that are ab ...
When the authors of this book asked me to write the foreword of
their work on the digital enterprise, I immediately thought that it was
one more document on a fashionable topic in the technology and the
business world of the 21st Century often addressed by consulting
firms, some of which have aspire ...
Wireless Fidelity (Wi-Fi) networks have become mainstream over the last few years. What
started out as cable replacement for static desktops in indoor networks has been extended
to fully mobile broadband applications involving moving vehicles, high-speed trains, and
even airplanes.
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling
and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations.
For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF
compon ...
his research aims at creating broadband tunable, fully integrated filters for the application of
cognitive radio and signal classification receivers. The approach under study is the N-path filter
technique which is capable of translating a baseband impedance to a reference frequency creating
a tunab ...

deploy Live Communications Server 2005 SP1 on a physical or virtual server running Microsoft
Windows Server 2003. To run Communicator 2005, you will need a physical or virtual PC running
Windows XP ...
Thanks to the advances in micromachining fabrication technologies and significant
cost reduction due to mass production, miniature sensors of angular rate, or
gyroscopes, found their way into the everyday life of every user of modern gadgets,
such as smart phones, tablets or even wristwatches. Often ...
Of the various applications that satellites have been used for, one of
the most promising is that of global positioning. Made possible by
Global Navigation Satellite Systems, global positioning enables any
user to know his or her exact position on Earth. Nowadays, the only
fully functioning system i ...
MIT App Inventor is an innovative beginner’s introduction to programming and app
creation that transforms the complex language of text-based coding into visual, drag-and-
drop building blocks. The simple graphical interface grants even an inexperienced novice
the ability to create a basic, fully fu ...
The PW4554 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger.The charger uses a CC/CV charge profile required by Li-ion battery. The charger accepts an inputvoltage up to 24V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V,to ...
