Saving IQ Data in File Using GNU Radio and USRP B210

[PHDHA]

I am currently working on detecting NB-IoT signals using the USRP B210. After converting the signal to baseband and obtaining the digital IQ data via the ADC, I need to save the IQ data as a file. This file will then be used as digital input for the Virtex-7 FPGA to decode the data. I am using GNU Radio for this project.

I would be grateful if you could help me with this.

Hi PHDHA,

A simple setup to receive IQ samples from the USRP and then storing them in a file can be seen in this image:

The USRP Source block instructs the USRP to receive samples, while the File Sink block stores the samples in a file.

Best regards,

Leonard

Hi PHDHA,

If you have more questions regarding this, let me know!

For my answer, I assumed you use the flowgraph UI. A C or Python solution would be different ofcourse.
