RAIN attenuation is a major concern in satellite links operating in Ka-band, and fade mitigation comes at the expense of higher satellite resource consumption, such as bandwidth and power. An accurate estimation of these resources is essential for the satellite service providers’ overall service pricing. However, the spatial correlation of rain fade introduces a high level of model complexity, such that its impact on resource consumption is currently unknown. This paper proposes a satellite resource dimensioning process that accounts for such a correlation. Firstly, broadband satellite networks and service level agreements are introduced along with existing dimensioning techniques. Then, a resource demand model is presented, from a single terminal to a system-wide point of view. Subsequently, the satellite resource dimensioning problem is formulated as a quantile estimation problem. A Monte Carlo process is proposed to solve the problem for a given relative confidence interval using spatially correlated rain fade sample generators. Finally, residential and enterprise broadband satellite simulation scenarios are thoroughly presented and numerical results are provided. Comparing these results against optimistic (independent) and pessimistic (fully correlated) rain fade assumptions found in existing dimensioning techniques, the proposed method shows that these techniques can underestimate by up to 70% or overestimate by up to 60% the satellite resource consumption.

“…The approach also fails to take into account spatial correlation, as the optimization variables are based solely on individual terminal complementary CDFs (CCDFs) and not on the correlation matrix. Their work has been continued by us in [20]. A solution for the carrier plan problem has been presented in the form of a MILP formulation that accounts for spatially correlated rain fade and the terminal's QoS needs.…”

“…Meanwhile, gateways are required to manage the NTN, and can connect the NTN with terrestrial networks [7,8]. Due to the severe signal attenuation of space-to-ground links, gateways are often equipped with high transmit-receive gain antennas, which have the ability to amplify UTs' signals in SATCOM star networks [9][10][11].…”

Satellite communication networks have gradually been recognized as an effective way to enhance the ground-based wireless communication. Considering the weight restriction of payloads, multi-antenna technologies have recently come into use on satellite platforms, and are capable of generating beams flexibly to provide services. To avoid incurring interferences, adjacent beams are designed to take different spectral resources. Unfortunately, this may limit the simultaneously accessed terminals since the spectrum cannot be fully used. In this paper, we propose a spectrum-saving transmission method in a satellite star network, where terminals communicate with each other through the hub station. Taking advantage of the great transmission capability differences of the hub station and terminals, we could allocate them the same spectral resources. Specifically, it is not necessary to use exclusive frequency bands for terminals.The proposed method can play a significant role when large numbers of users need to access the system with limited spectrum resource. To give a deep insight into the spectrum-saving method, the expressions of ergodic sum-rate are provided, and the impact of the number of accessed terminals is further analyzed. Simulation results validate the advantage of the proposed method in terms of bit error rate and ergodic sum rate.
