“…In this decade, the introduction of BB SoC and, most recently, RF programmable transceiver SoC can fulfill the early promise. Also, open source simulation tool such as GNURadio [35] is widely used to implement low-cost digital beacon receiver based on SDR [37], Emergency Managers Weather Information Network (EMWIN) and Low-Rate Information Transmission (LRIT) Software Receiver using GNURadio [41]. GNURadio was used in this research initially to understand the working of the existing/generated filters, channel codes, synchronization elements, equalisers, demodulators, decoders and other processing blocks using prerecorded or generated data as addressed in [33].…”

Abstract-The ongoing evolution in constellation/formation of CubeS ats along with steadily increasing number of satellites deployed in Lower Earth Orbit (LEO), demands a generic reconfigurable multimode communication platforms. As the number of satellites increase, the existing protocols combined with the trend to build one control station per CubeS at become a bottle neck for existing communication methods to support data volumes from these spacecraft at any given time. This paper explores the S oftware Defined Radio (S DR) architecture for the purposes of supporting multiple-signals from multiple-satelli tes , deploying mobile and/or distributed ground station nodes to increase the access time of the spacecraft and enabling a future S DR for Distributed S atellite S ystems (DSS). Performance results of differing software transceiver blocks and the decoding success rates are analysed for varied symbol rates over different cores to inform on bottlenecks for Field Programmable Gate Array (FPGA) acceleration. Further, an embedded system architecture is proposed based on these results favouring the ground station which supports the transition from single satellite communication to multi-satellite communications.

“…In [12], a GNU-radio based multi-channel voice transceiver has been developed and tested in emergency rescue scenarios. A software receiver for the emergency weather information network (EWIN) fully implemented on GNU-radio platforms is presented in [13]. In [14], GNU-radio tools demonstrated their capability to support the software integration of satellite radio localization and terrestrial communications in emergency scenarios (like disaster relief, terrorist attacks) where both satellite navigation and terrestrial network infrastructures are severely impaired.…”

In the last years there has been a growing interest in software-defined radio communication systems (SDR). SDR technologies are attractive for communication systems because of their reconfigurable capabilities. Due to the complexity of real scenarios, usually characterized by multipath propagation and heterogeneous interfering sources, the antenna plays a key role. It is demonstrated by literature that the use of reconfigurable antennas (known also as smart antennas) could dramatically improve system performance. In this paper, we propose a compact and low-cost antenna array, based on microchip antennas, which will be integrated with a low-cost GNU-radio SDR testbed. The proposed antenna reconfigures its radiation characteristics, turning on/off the array elements, by means of radio frequency (RF) switches. The antenna is software controlled by means of a suitable optimization technique that maximizes the signal-to-noise ratio (SNR). Test results can prove the capability of the proposed antenna to improve the performance of SDR telecommunication systems in terms of increased SNR and reduced bit error rate.
