Description

Overview

This example demodulates a continuous differential M-PSK modulated signal.

 

 

Description

This example demodulates a continuous differential M-PSK modulated signal, and tracks timing and frequency offset. In addition, if the transmitted bit sequence is a Galois PN sequence, then bit error rate can be measured.

 

 

Steps to Implement or Execute Code

  1. Unzip and open the project.
  2. Deploy the FPGA bitfile to your PXIe-5641R.
  3. Open host VI and customize Rx configuration.
  4. Run host VI.

 

 

Requirements

Software

LabVIEW FPGA 2010

LabVIEW FPGA RF Communications Library 3.0 available on NI Labs

 

Hardware

PXIe-5641R

This is a very good example to understanding the DBPSK algorithm.

Hello every one,

             i am using this example  LV2010 5641R DPSK demodulator .when i compile this on NI PXie 5641R i get the following error shown above.it keeps on compiling for about 38 minutes mentioning generating cores.then this error appears.so any one knowing about this error.

My system RAM is 4 GB .

thankyou.

Hi jadoon,

Please try applying this hotfix - http://joule.ni.com/nidu/cds/view/p/id/3864.  If that doesn't work, I would advise you to call support at (866) ASK-MYNI or post in our forums.  Our systems don't streamline the ability to support you through the comments section of these documents.

Good luck!

Regards,
Chris Elliott
