基于FPGA技术的短波数字接收模块的实现

介绍一款基于FPGA技术的短波数字接收模块的实现方法，通过对FPGA芯片的编程替代专用的数字信号处理芯片，完成对中频信号的解调。同时FPGA的可重载性为设备后续扩展留有余地，能够大大提高设备的使用寿命，可以有效控制系统的建设成本。按照该方案实现的接收模块具有接口灵活，维护成本低和工程化方便的特点。通过对样机的实际测试，其性能、指标、功能和人机接口等方面与同类产品相比均有相当的改观。

Realization of Short-wave Band Receiver Based on FPGA Technology

It's an introduction of a realization of digital receiver shortwave module based FPGA.It makes demodulation on instermediate frequency signal by programmed on FPGA instead of DSP chips.Overloading of the FPGA can be extended up to leave room for the device,which can improve the life of the equipment greatly and control construction costs effectively.The receiver module according to the program has flexible interface,low maintenance costs and engineering and convenient features.Compared with similar products...
