【摘要】在卫星通信中,由于载荷的体积和重量受限严重,因此,对星载通信转发器的性能具有很高的要求,卫星信道化器技术是解决该问题的重要手段。主要讨论数字信道化器的总体实现架构以及在其中具有重要角色的子信道滤波器的设计方法与技术,对数字信道化器的整体实现具有重要意义。更多还原

【Abstract】 In the satellite communications, there were very high performance requirements for the satellite transponder due to the restrictions of the volume and weight of the load, and the satellite channelization technique was an important means to solve this problem. The overall implementation structure and the sub-channel filter design method which played a serious role in the system were discussed. It has important practical significance to the overall implementation of the digital channelization.更多还原
