“…For higher-spectrum efficiency, a hybrid modulation scheme can be used, where two parameters of the carrier, i.e., the frequency and phase are simultaneously modulated. For instance, in [112], Vertat et al proposed a hybrid M -frequency shift keying (FSK)/Differential-QPSK modulation technique, leading to higher spectrum efficiency compared to M -FSK. Another means of achieving highly-efficient CubeSat communication systems is through the joint design of higherorder modulation schemes with error-correcting codes, usually referred to as coded modulation frameworks, for example, trellis coded modulation (TCM) [113].…”

Given the increasing number of space-related applications, research in the emerging space industry is becoming more and more attractive. One compelling area of current space research is the design of miniaturized satellites, known as Cube-Sats, which are enticing because of their numerous applications and low design-and-deployment cost. The new paradigm of connected space through CubeSats makes possible a wide range of applications, such as Earth remote sensing, space exploration, and rural connectivity. CubeSats further provide a complementary connectivity solution to the pervasive Internet of Things (IoT) networks, leading to a globally connected cyber-physical system. This paper presents a holistic overview of various aspects of CubeSat missions and provides a thorough review of the topic from both academic and industrial perspectives. We further present recent advances in the area of CubeSat communications, with an emphasis on constellation-and-coverage issues, channel modeling, modulation and coding, and networking. Finally, we identify several future research directions for CubeSat communications, including Internet of space things, low-power long-range networks, and machine learning for CubeSat resource allocation.

The research in the emerging space industry is becoming more and more attractive, given the increasing number of space-related applications. One primary entity of current space research is the design of miniaturized satellites, known as CubeSats, due to their numerous applications and low design and deployment cost. The new paradigm of connected space through CubeSats enables a wide range of applications such as Earth remote sensing, space exploration, and rural connectivity. CubeSats further provide a complimentary connectivity solution to the pervasive Internet of things (IoT) networks, leading to a globally connected cyber-physical system. This paper presents a holistic overview of different aspects of CubeSat missions, and provides a thorough review on the topic, both from academic and industrial perspectives. We further present the recent advances in the area of CubeSats communications with an emphasis on constellation and coverage issues, channel modeling, modulation and coding, and networking. The paper finally identifies several future research directions on CubeSats communications, namely Internet of space things, low power long range networks, machine learning for resource allocation in CubeSats, etc.
