A system block diagram shows how a LUT based NCO is used to generate the sine wave with varying frequency and then with varying phase. Extensive testing and its results are discussed to verify the ...

In this application the modulation scheme targets Altera’s Cyclone-IV FPGA populated on a DE2-115 development board from Terasic and an HSMC (High Speed Mezzanine Card). A system block diagram shows ...

Results: NTT and their partners have developed a detection and control mechanism for the CEO signal (fceo), which has been difficult for electro-optic modulation-based optical frequency comb.
