Mixed-integer linear programming for multibeam satellite systems design: Application to the beam layout optimization

Satellite traffic analysis and characterization are motivated by a key observation, that is, the traffic pattern of one beam is different from another [15]. Hence, the proposed

CONCLUSIONS In this paper, an improved 2 mrad crossing angle scheme has been presented, including carefully optimized FDs, integration into the final focus and design of the

Beam hopping (BH) for satellite systems has been proposed as a promising technological enabler to provide a high level of flexibility to manage irregular and time variant

The contributions made in this study are follows: we model the deterministic OT scheduling problem, integrating allocation and sequencing decisions in the same model; we

To solve the problem, we design a suboptimal algorithm to firstly decompose the original problem into multiple convex subproblems by fixing power allocation for each beam, and

As mentioned before, in general the objective function f ( r ) is non-convex which makes the whole problem difficult even with linear power constraints only. There has been a

(2) We proposed a new optimized data layout scheme called ALOR, which achieves an appropriate layout of data and Raft leaders in a heterogeneous dis- tributed key-value storage

To achieve the best performance on a heterogeneous many-core system, programmers are required to take considerable effort to transform the data layout to enable data
