To that end, we first develop a multibeam satellite model that accounts for prop-agation effects, interference among beams, and atmospheric attenuation. Next, we formulate the joint power …

The joint bandwidth and power allocation iterative algorithm based on duality theory was proposed to obtain the optimal solution of satellite power and bandwidth resources in a multi-spot-beam …

follows: ”How should the satellite constellation orbit, altitude, and elevation angle selections be sized for a given market demand distribution, satellite transmit power, antenna size, channel …

Dec 19, 2021 · In order to solve the constraints of traditional frame generation algorithm on the multi-data transmission rate of satellite navigation system effectively, optimize the system …

Therefore, this thesis aims to develop a new method- ology of power and bandwidth allocation in multibeam satellite systems taking into account interferences and to investigate the …

The high-level system block diagram considered is shown in Figure 1. The first block in the chain is the gateway modulator which is described in detail in Section 2.1. The RF output signal is …

• A good short bandwidth efficient modulation code (trellis or block) is used as the inner code and rela-tively powerful Reed-Solomon (RS) code is used as the outer code. • With properly …
