Ka波段多波束卫星联合优化功率分配算法
A joint optimum power allocation algorithm for Ka-band multi-beam satellite system
摘要
Abstract
Power allocation for the downlink spot beam caused by rain attenuation does not match the actual demand in Ka-band multi-beam satellite system,a joint optimum power allocation algorithm (JOPA)is proposed.The algorithm is based on the actual rain attenuation and the minimum traffic demand,the Lagrange duality theory and the subgradient method are used to optimize the problem.The simulation results show that JOPA achieves the maximization of total capacity and the fairness of power allocation among different spot beams without the waste of resources.关键词
