摘要
提出用FPGA器件实现一个完整的数字下变频系统的方法,给出VerilogHDL语言的描述,实现高效的运算结构,减小了运算量,提高了系统性能。本系统已经在某型气象雷达的数字接收系统中得到采用,参数得到验证,性能优良。
A method of using FPGA device to realize digital down converting system is presented, and the description of VerilogHDL language is given so that the high efficiency operational structure is fulfilled, and the operand is reduced and the system performance is enhanced. This method has been adopted in the digital receiving subsystem of a certain meteorological radar, and the specifications are verified and the performance is perfect.
