QPSK transceiver

[bc2007]

Has anyone built a QPSK transceiver using the NI-5640R with the NI Communications System Design Pioneer Program? I have been modifying one of the example VI's that came with the package but so for I'm having no luck communicating with a standard satellite modem.

If anyone has built an I.F. transceiver for such an application I would be interested in discussing the build and similiar problems that I am seeing. I would list the various problems here but it's a long list.

Hello jIgnasa,

I apologize for the delay in reply.

Could you please elaborate a little more on the problem you are facing?  What have you built till now? Have you already implemented the transceiver which is not communicating now?

What are you trying to implement on the FPGA and what portion on the host?

Sastry,

Do you have an email address so we can communicate directly?

Tks,

Hello,
Aman here, i want to do the BPSK n QPSK Modulation, please help me out if u did that using the NI-5640R with the NI Communications System Design. i m new for the Labview FPGA, previous i finished all that in labview worktool with out FPGA but i m getting problem to complete in labview FPGA.
my project is on hold bcoz of these plz reply me soon.

thanks

Hi Aman,
I have worked on BPSK/QPSK demodulators using NI-5640R with LV-FPGA. If you can let me know in detail about the problems you are facing, I would be happy to help you out.

Hello  Ananth..

 i m working on a project which is require all the Digital Modulations(BPSK,QPSK,FSK.GMSK etc.), for this i have to take carrier Frequency(mark frequrncy) as a 21.4 MHz for all modulations. But i m new for the LV FPGA PCI 5640 R, i m not able to understnd hw to make FPGA n host for these kind of Modulations, previously i finished all modulations on Labview Work tool (with out FPGA), so plz help me out in that to solve my problems. if u have any Example for these modulation using LV FPGA 5640 R plz send it to me so that i can understnad better, pla send ur e-mail id so that we can contact direct, my e-mail id is aman.sanghi@gmail.com

thanks
Aman Sanghi.
