The bandwidth and latency demands driven by 5G wireless networks are putting a focus on analog radio-over-fiber techniques as promising candidate for broadband optical fronthauling. In contrast to intensity modulation / direct detection systems, they commonly adopted mobile fronthaul links due their simplicity, we exploring migration option towards coherent transmission. A simplified homodyne r...

We demonstrate the feasibility of fingerprinting the radio of wireless sensor nodes (Chipcon 1000 radio, 433MHz). We show that, with this type of devices, a receiver can create device radio fingerprints and subsequently identify origins of messages exchanged between the devices, even if message contents and device identifiers are hidden. We further analyze the implications of device fingerprint...

The survey paper identifies the enabling technologies and research areas in radio frequency engineering that may facilitate the development of Software Defined Radios (SDR). Receiver architectures are also discussed and their viability for a reconfigurable radio application is investigated. The paper also reviews several important techniques based on Software Defined Radios.

In the coming years, many more satellite positioning signals will become available to civilian users. In addition to the L2 and L5 signals of GPS is the array of different signals that will be broadcast by Galileo. A Galileo receiver will be required to be fully compatible with GPS, so the receiver will need to be sophisticated enough to receive and process all of these signals simultaneously. ...

Abstract-In this research work, the problem of congestion that leads to dropped calls at GSM cell sites and drastic reduction in network capacity is addressed. We designed a novel GSM base station architecture named Nomadic Base Station (NBS) which is based on Software Defined Radio (SDR) architecture and simulated the LNA for its receiver front-end. The NBS receiver LNA selects and amplifies G...
