摘要
提出了一种基于Cordic算法的数字下变频方法,阐述了Cordic算法的基本原理,为了提高运算速度和减小精度,文中重点叙述了改进型的Cordic算法原理,并通过原理进行了FPGA设计,最后给出了QuartusII仿真结果,并在Matlab中得到了验证。
The paper puts forward a Digital Down Conversion method based on cordic algorithm. The basic principles of cordic algorithm are elaborated. The emphasis is put on an improved cordic algorithm for faster operation and smaller precision. A design with FPGA is presented and simulated with quartus Ⅱ. Simulation results are verified in matlab.
