I'm working with a small group of friends
on a project that we think would help us
much better understand system level
digital communications design. We are all
experienced digital designers, but not at
the sytem level.
What we want to build is a system that is
made up of 4 major parts: modulator,
upconverter, downconverter, and
demodulator. We plan on doing the
modulation and demodulation with a DSP
board. We want the output of the DSP
board to be a baseband analog signal. We
want to feed that baseband signal to black
box that does the upconversion and
transmission. Another black box on the
receive end will downcovert and output
another baseband signal. The downstream
DSP board will do its own gain control,
digital demodulation, and possibly output
