Modern trains act as Faraday cages making it challenging to provide high cellular data capacities to passengers. A solution is the deployment of linear cells along railway tracks, forming a cellular corridor. To provide a sufficiently high data capacity, m ...
Efficient and reliable spectrum sensing plays a critical role in cognitive radio networks. This paper presents a cooperative sequential detection scheme tominimize the average sensing time that is required to reach a detection decision. In the scheme, each ...
With the convergence of internet and wireless communications, a plethora of new services will originate. A natural application for cellular radio networks is that of radiolocation, in which the mobile unit can be positioned based on the signals received at ...
The Substrate Integrated Waveguide (SIW) technology is a very promising candidate to provide widespread commercial solutions for modern communications systems. Its main advantage is the possibility to integrate passive/active components and antennas in the ...
Surface Acoustic Wave (SAW) technology is omnipresent in the devices around us today, mainly used as passive bandpass filters in most radio systems like smartphones and TV antennas or as delay lines in telecommunications. More recently, the possibility to ...
A single GNSS antenna moving along a known trajectory can be used to synthesize a virtual array in order to apply spatial diversity techniques, e.g. beamforming. With these techniques, referred as synthetic aperture (SA) techniques, the receiver can mitiga ...
Nowadays, efficiency and productivity are fundamental concepts, in any kind of business. Although one can easily accept this as a known fact, one cannot easily identify which steps must be taken to achieve these goals. One approach consists of taking full ...
This paper presents a fully integrated remotely powered and addressable radio frequency identification (RFID) transponder working at 2.45 GHz. The achieved operating range at 4 W effective isotropically radiated power (EIRP) base-station transmit power is ...
In this work, a sub sampling receiver front end at 2.4 GHz with high Q filtering to perform channel selection at RF is presented. A low power solution for channel selection directly at RF is proposed in this work using pseudo-self-biased inverter amplifier ...
