Intro Comm. Systems Lab 9: BPSK

[salimask]

Hello everyone,

I'm trying to do lab 9 from NI Introductory Communications Systems. https://learn.ni.com/teach/resources/67/lab-9-binary-phase-shift-keying

However, I'm totally new to LabVIEW Communications. I know the basics in theory but its hard to put it into the software. For example I'm not aware of how to do the symbol mapping connectivity, frame...etc.

Any sort of help would be appreciated. 

Thanks,

There are quite a few steps and questions in that lab. Is there a specific question you are having problems answering or a step that you don't know how to do?

If you let us know exactly what step you are having trouble with and attach what you have tried so far we can help out.

Hi Jacobson, 

Thanks for your reply. Actually I need help with the first step so that I get familiar with the interface. I’m having trouble with the symbol mapping (how to assign bit value to a symbol). And how to connect it with the Upsampling module. I’ll keep trying from there.

I think you can use this idea,

"2*(input_bit)-1"

if input_bit is  0, it will be -1

if input_bit is 1, it will be 1
