Description
Software Defined Radio, streaming digitized IQ samples over a network, provides the framework for creating a distributed coherent network of receivers or emitters with the ability to locate (trilateration) or steer (electronic beam steering) the recorded and emitted signals over long baseline, assuming the transceivers are synchronized. Long range time and frequency distribution over Gb Ethernet networks is provided by the White Rabbit framework. We discuss how GNU Radio and White Rabbit, both intensively developed at FAIR following closely related objectives, might merge currently independent frameworks leading to distributed coherent signal processing. Example of carrier synthesis and distributed acquisition using off the shelf hardware will be used to demonstrate the proposed concepts.
