Linear Frequency Modulation Signal Generator Based on CORDIC Algorithm
Yang Wu · Dianzi qijian · 2013
In order to overcome the defects of traditional method of DDS based on the look-up table,which occupied more data storage units and reduced the operation speed and accuracy,this paper mainly studied and realized production of the linear frequency modulation signal based on CORDIC algorithm.A full pipeline direct digital synthesizer was built by using Verilog HDL.The linear frequency modulation signal was produced in combination with phase modulation of linear FM signal.The results of RTL simulation on ModelSim show that the method is correct.
