摘要
为了满足某高速卫星通信地球站调制解调器对多相插值滤波器的实际应用设计需要,分析了多相插值滤波器的一般设计原理,给出了一种多相插值滤波器的设计方法。采用VHDL语言TOP-DOWN设计方法,用XILINXVIRTEX-xv600系列FPGA进行了实现,对FPGA设计进行了仿真与测试。给出了部分仿真、实际应用测试结果。证明了设计的多相插值滤波器的正确性与可行性。
To meet the requirements of the multi-phase interpolation filter of a high data rate satellite modem, this paper analyses the basic design principle and presents a design method of a multi-phase interpolation filter. The FPGA design is implemented with VHDL TOP-DOWN method in a XILINX VIRTEX-xv600 chip. Finally, part simulation and application test results are given and the correctness and feasibility of the filter is demonstrated.
