In recent years, multi-spot-beam satellite communication systems have played a key role in global seamless communication.
However, satellite power resources are scarce and expensive, due to the limitations of satellite platform.
Therefore, this paper proposes optimizing the power allocation of each user in order to improve the power utilization efficiency.
Initially the capacity allocated to each user is calculated according to the satellite link budget equations, which can be achieved in the practical satellite communication systems.
The problem of power allocation is then formulated as a convex optimization, taking account of a trade-off between the maximization of the total system capacity and the fairness of power allocation amongst the users.
Finally, an iterative algorithm based on the duality theory is proposed to obtain the optimal solution to the optimization.
Compared with the traditional uniform resource allocation or proportional resource allocation algorithms, the proposed optimal power allocation algorithm improves the fairness of power allocation amongst the users.
Moreover, the computational complexity of the proposed algorithm is linear with both the numbers of the spot beams and users.
As a result, the proposed power allocation algorithm is easy to be implemented in practice.
