摘要
数字下变频技术是软件无线电的核心技术之一,本文首先介绍了数字下变频器的原理,然后主要讨论了基于FPGA的数字下变频实现方法。FPGA具有大容量,可编程的特性,以及设计和修改方面的灵活性,使得用FPGA来代替专用下变频芯片更加符合软件无线电的思想。
Digtal DownConverter is one of the core technologies of software radio, this paper introduces the principle of Digtal Down Converter, and discuss the realizable method based on FPGA in detail. FPGA has the abundant resources and programmable characteristic, also the agility in designing and modification, thus it' s coincident with the software radio idea using FPGA to replace special Digtal DownConverter chip.
