A Fast Acquisition Algorithm Based on High Sampling Rate FFT for LEO Satellite Signalse algorithm can realize the frequency estimation and fast acquisition of the signal when the frequency offset is 4 times the symbol rate. Compared with the traditional method, the algorithm greatly improves the acquisition bandwidth and speed.

Optimization of Joint Power and Bandwidth Allocation for Multiple Users in a Multi-spot-Beam Satelliosed joint allocation algorithm improves the total system capacity and the fairness between users. A suboptimal algorithm is also proposed, to further reduce computational complexity, with a performance level much closer to that of the optimal allocation algorithm.

A Networking Transmission Method in the Case of Limited Satellite Transceiver equal connectivity opportunities, but also reduces the delay of end-to-end paths. Finally, relying on the iridium constellation, under the connectivity fairness topology configuration method, we simulate and analyze the algorithm, and prove that the network transmission has a lower path delay than the satellite over-the-top transmission.

Optimization of Joint Power and Bandwidth Allocation for Multiple Users in a Multi-spot-Beam Satellirent spot beams and constructing flexible service networks. As the on-board resources of bandwidth and power in a multi-spot-system are scarce, it is important to enhance the resource utilization efficiency. To this end, this paper initially presents the formulation of the problem of joint power and
