“…This paper is an extension of the work carried out in [33] and [34] where a novel SDR architecture on an embedded system is proposed as seen in section 2. The implementation and validation process of the proposed transceiver architecture is briefed in section 3 (more details on transceiver implementation and validation can be found in [34]).…”

“…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.

“…Moreover, the heterogeneity of the potential application scenarios, and therefore the flexibility needed on the receiver side, makes the SDR technology [11] suitable for the quick adaptation of the receiver to different physical layers, maximizing the opportunity to disseminate multiple information messages all over the world [12]. …”

Effective answers to the major problems in society can be achieved by resorting to the integration of telecommunication platforms, heterogeneous systems of localization, and sensing capabilities and intelligent objects [1]. Particularly, the pursuit of long term technological solutions has to be made with the support of a revolutionary multidisciplinary approach, especially in the areas of transport, smart environments, quality of life, security, etc.As a result, new and more intelligent services will become available, allowing the realization of smart contexts for what concerns home, building, cities, work-places, and implementing new concepts as ambient intelligence, ambient assistant living, ubiquitous computing, context awareness, and many more. This pervasive communication ecosystem will solve many, if not most, problems in our life, by increasing security and safety perception and improving interaction and conditions of activities; information and communications technologies will be a pillar of this society evolution by providing a complex net of information exchanges and exploiting the big data that are involved in the procedures [2].Moreover, the satellite segment will contribute significantly to the evolution of the services by means of the synergistic use of communication, positioning, and monitoring techniques: this objective will be realized by means of meshed heterogeneous architectures [2] that can afford remarkable systems and networks performance. At the same time, some of the envisaged future services such as the global tracking, monitoring, and maintaining of some specific assets or contexts don't mandatorily request the implementation of classic wireless or satellite communication systems which are subject to coverage and cost limitations; conversely, the uprising Machine-to-Machine (M2M) and Internet of Things paradigms seem to be more appropriate in such scenarios where a global packet connectivity has to be afforded in order to permit the exchange of information between the network and the ultimate users but the requirements in terms of data-rate and latency are not stringent [3], [4].On the other hand, this strategy can be successful if some operating conditions and key factors can be granted; particularly, the following conditions are compelling:C this strategy has to be general, i.e., a very large set of future services has to rely on it, even if their requirements are rather diversified and even divergent;C the communications, both within the system and between the system and the external world, will have to be highly efficient and to deliver all the necessary information in due time, where needed, with required quality of service (QoS) and energy consumption.Among the systems which allow the achievement of both of these goals, the new class of "SmallSats" also affords the reduction of the implementation costs and the increase of system availability because of their recent exponential growth [5], [6], [7]. As a result, the exploitation of SmallSats solutions, such as the CubeSat, as a b...
