This book targets major issues in terrestrial-satellite communication
networks and presents the solutions. While the terrestrial networks can
achieve high-speed data service at low cost, satellite based access is
one way to complement terrestrial based networks to ensure ubiquitous,
100% geographic coverage. The coexistence and cooperation between
terrestrial and satellite networks are of great potential in future
communication networks, and satellite radio access networks has already
been considered in the fifth-generation (5G) networks to be supported
for phase 2. Therefore, it is important to study the architectures of
terrestrial-satellite networks, as well as the possible techniques and
challenges.
The authors introduce the technique of beamforming in satellite
communication systems, which is an efficient transmitting method for
multiple access, and they discuss the main challenges as well as
prospective applications. The authors introduce possible methods for
interference cancelation reception in terrestrial-satellite
communication networks when reusing the frequency band between the two
networks. Due to the limitation of spectrum resources, spectrum sharing
will become one of the important issues in terrestrial-satellite
communication networks. The problems of spectrum coexistence between GEO
and Terrestrial Systems and between GEO and NEGO systems are also
discussed.
Finally, taking both the two system into consideration, the resource
allocation problem will be more complex due to the coupling between
resources and the interference. Based on this, the authors propose
several resource allocation schemes in different scenarios of
terrestrial-satellite communication networks, which can optimize the
capacity performance of the system. The expected audience for this book
includes (but not limited to) graduate students, professors,
researchers, scientists, practitioners, engineers, industry managers,
and government researchers working in the field of satellite
communications and networks.
