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...
gr4-packet-modem is a packet-based modem application that is being implemented from scratch for GNU Radio 4.0. The goal of this project is twofold: it serves as a use case to test and benchmark the GNU Radio 4.0 runtime in a realistic digital communications application, and it provides an example of a full system that users will be able to study and customize to their needs. The modem uses...
High speed data transmission has increasingly become important in satellite communications due to the exponential growth of generated data with the advancement of observation technology such as ultra-high definition 4K cameras. This poses quite a challenge for new space applications, which focus on short development span and cost-effectiveness, by pushing the limits of receiver designs and...
Low Earth Orbit (LEO) satellite networks are pivotal for global communications, particularly in remote and underserved areas. The Long Range (LoRa) communication protocol, primarily utilized in IoT satellite networks due to its low power consumption and long-range capabilities, emerges as an ideal candidate for enhancing LEO communications. This study presents the development of an adaptive...
