卫星群中采用毫米波（mmWave）波束定向传输，可以有效避免卫星工作在同一频段带来的干扰问题。但由于卫星簇拓扑的动态变化以及卫星传输报文的随机性，仍然会存在干扰。在本文中，在波束域方面，提出波束偏置作为干扰抑制方案，以最大化网络的可实现速率。具体来说，从资源管理的角度，采用增强遗传算法来搜索多波束接收高级毫米波中每个波束的最佳波束偏置角。仿真结果表明，与传统的毫米波通信多波束接收方案相比，所提出的方案可以显着提高可达速率。
The directional transmission of millimeter wave (mmWave) beam is applied in the satellite cluster, which can efficiently avoid the interference problem caused by the satellites working in the same frequency band. However, due to the dynamic change of the satellite cluster topology and the randomness of the message transmitted by satellite, there will still be interference. In this paper, in terms of beam domain, beam biasing is proposed as an interference mitigation scheme to maximize the achievable rate of the network. Specifically, in the view of resource management, enhanced genetic algorithms is applied to search for the optimal beam bias angle of every beam in mmWave with multi-beam receiving senior. Simulation results show that the proposed schemes can significantly improve the achievable rate compared with the conventional multi-beam receiving scheme for mmWave communication.
