摘要
针对海事五代(Inmarsat-5)高通量卫星信号的特点,结合卫星前向多波束信号接收处理的需求,设计了一种基于专用处理芯片的接收处理设备,该设备采用子板+载板的结构形式以及ASIC+FPGA+DSP的架构。经过实星信号接收测试,该设备能够实现Inmarsat-5高通量卫星固定点波束信号和高容量点波束信号的实时接收处理,具有工作稳定、接口丰富、软件可升级等优点,可以广泛用于各种相同信号体制的高通量卫星信号接收机。
This paper analyzes the characteristic of Inmarsat-5 HTS signals. According to the forward multibeam signal receivingneeds,a design of receiver based on ASIC is presented. The receiver adopts a structure of the sub board ＋ load board and anarchitecture of ASIC ＋ FPGA ＋DSP. In a real reception test,the receiver realizes a real time reception of the fixed spot beam signal andthe high capacity spot beam signal. The receiver has good extensibility and flexibility and it can be applied to the communication orreconnaissance receiver for HTS.
