I am looking for a digital design or technique that I can use to
transmit the 48bit of data at 1.5MHz frequncy wirelessly. So, what I
gathered so far is that a digital frequncy modulator can be made using
a FPGA and the demodulator can also be made using FPGA. Am I right ,
if yes then i need more guidance , some literature to understand
exaclty how can I do this? The thing that I do not still understand
that If I am right about the FPGA based frequency modulator and
domodulator then how would I design the wireless part of the system?
After re-reading some of your posts, it seems clear that your data
rate is 72 Mbps. It would help to know if this is a one-off
(feasibility) or a design project ... Since you already have a Spartan
on the transmit side, you can use it as a modulator (e.g QAM),
followed by an up-converter, and use another FPGA after down-
conversion on the receive side. I think questions about what "chips"
to use for the RF (or optical) section might be more productive after
we know more about the cost / size and power constraints.
