Hi Rupen,
I'm not 100% sure what you are looking for? I think you are referring to software.
Have you looked at the NI Modulation Toolkit for LabVIEW? This expands the functionality of LabVIEW with functions and tools for signal generation, analysis, visualisation and processing of standard and custom modulation formats.
This will allow you to generate a bitstream and modulate or demodulate data with standard formats.
Take a look at the link above that will give more information about the toolkit and extra links to the manuals for it. If you have any questions then please let me know.
