dds dither
Hei Guys,
I am currently working on the AWG project, and I am in charge of the DDS module, we need to Implement Phase Dither after the trunction of accumulator and before the phase-attitude converter in order to increase SFDR.
There are many papers about the spur-decreae by using phase dither like PN sequencial or M sequencial, etc, most of those do not mention how to realization..
I do not know how to find and setup the correct model of hte Phase Dither to simulink DDS system in matlab, further more, I also need to implement the phase dither in FPGA.
So, need you guys to help me..
Thanks very much
