NiUSRP Modulation Toolkit PSK Example

[msacikgoz]

Hi,

I am tyring to figure out NiUSRP modulation toolkit examples and I want to transmit and receive audio signal.I get bit stream of audio signal and I put it in a text file because BB-PSK generation vi input is text.I ran niUSRP EX PSK Tx.vi and  niUSRP EX PSK Rx.vi when I observed that Constellation Graph of transmitter matched with receiver's Constellation Graph but I didn't listen the received signal after demodulation.Can you help me?

Audio signal properties: sample rate 8k Hz and 16 bits per sample.

I have an error something like that and I shared wrong text file my previous post so I'm sharing again.Also I realized that transmit bits and receive bits didn't match so I am waiting answer for my problem .

Hello,

It looks like the example that you mentioned is not intended to generate any sound but create a spreadsheet file. There are some other examples that you can use as a guide to add this feature. These examples are located in the path shown below. As you have mention, you needed to create a bit stream of audio signal in order to transmit the data. Now, in order to be able to reproduce the audio you will need to do the invert procedure.
