BPSK modulation

[Ktim]

Hi,

I am having problem designing the BPSK signal whose central frequency (modulation frequency) changes over time and transverse over certain required bandwidth by the multiple of 25 kHz.

I found example vi in lab View communication suite for PSK modulation but I can just change central frequency manually.

Can you suggest me anything on how will I be able to change frequency over certain time frame at the interval of 25 kHz?

Below is the example I am running.

Thanks,

Ktim

Hello Ktim!

Out of curiosity, do you need to use LabVIEW Communications?  Or would you be open to using LabVIEW?  The reason I ask is because the Modulation Toolkit has BPSK examples that you can modify once you download it to your computer.  Below is some more information on the toolkit!

I hope this helps!

Hi Casey,

Can I use LabView for running my VI in USRP? I am using NI USRP N210 for transmission and reception of the signal.

Thanks,

Ktim

Hello Ktim!

You can use the USRP in LabVIEW by downloading the NI-USRP driver!  I have included a link below to the NI-USRP driver for Windows.

NI-USRP Driver for Windows - https://www.ni.com/en/support/downloads/drivers/download.ni-usrp.html

Additionally, upon downloading the driver, several USRP examples, both Rx and Tx, will also download that you can use.  You should also be able to incorporate the Modulation toolkit examples with the USRP examples.

Best,
