Implementation of DDWS-Based Complicated Waveform Generators

To overcome disadvantages of existing general signal generators,including long setup time and poor synthesizing of wideband complex signals,an implementation method is presented based on software radio and DDWS techniques.High performance DDS units are leveraged to generate frequency agile clock signals,large-capacity FPGAs are utilized to implement sequence synthesis,and ARM processors are used to realize the synthesis algorithm based on material waveforms.Experiments indicate that this method can improve complex waveform synthesis and shorten the setup time.
