摘要
文章提出一种短波宽带中频信号数字化实现方法。先对宽带中频信号进行带通采样。为保证多相滤波信道化工程实现,提出双FPGA协处理架构。之后对降采样低通滤波和多相滤波信道化实现方案进行资源分析,得出一种最佳的宽带中频信号数字化实现方法。
In this paper,a digital realization method of HF if signal is proposed.First,bandpass sampling of wideband if signal is carried out.In order to ensure the channelization of multiphase filtering,a dual FPGA coprocessing architecture is proposed.Then,resource analysis is carried out for down-sampling low-pass filtering and poly-phase filtering channelization,and an optimal digital realization method for wideband intermediate frequency signals is obtained.
