Student Projects with Wes Swartz for 2000-2001

Design of a digitally controlled transmitter for generating various RF test signals

http://people.ece.cornell.edu/wes/Projects

This project completed.

The use of a "software" radio built around new digital ICs requires a complemetary transmitter system. The goal is to design a "software" digital transmitter that can generate various modulation schemes that can be demodulated with software receivers being designed as a separate project.

There are a number of integrated circuits from Analog Devices that should provide most of the functionality. (See part numbers below.) Prototyping boards with these ICs may be available (we should check).

Specific tasks:

  • Check on availability of prototyping boards. Acquire?
  • Design any additional clocking, power supply, control circuits, as needed.
  • Design user interface (software).
  • Design several modulation schemes for demonstration purposes.
  • Evaluate performance.
  • Document.

    Parts to consider:

  • AD6622 65 MSPS, Quad Transmit Signal Processor.
  • AD9754 14-bit DAC.
  • AD9854 Digitally-programmable I & Q synthesizer.
  • AD9850 Digitally-programmable frequency synthesizer and clock generator.
  • AD9851 Digitally-programmable frequency synthesizer and clock generator. Driver, Program.
  • AD9852 Digitally-programmable synthesizer.
  • AD9853 Digital modulator.
  • AD9856 Quadrature upconverter.

    Students assigned:

  • Francis Cheong
  • Frank Lui (Systems)
