Abstract: Abstract 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.
