WebFeb 17, 2024 · A common arrangement is to use the QT GUI Sink 's output message port to connect to the USRP Source's input port, so that when a user double-clicks within the GUI to change frequency, the change gets propagated to the USRP device. The Example … WebThen in order to interface USRP with gnuradio you would need to flash your NI USRP with correct image accordingly for which you can follow this link. After USRP gets detected by GNURadio, make a simple block diagram in GRC for PSK transmitter random source. Fig. …
WebApr 26, 2012 · The transmit side: Wav source --> Packet encoder --> GMSK Mod --> UHD sink. The receiver side: UHD source --> GMSK Demod --> Packet decoder --> Audio sink. (samp_rate 48K). I think if the sound received on the receiver is the same as the wav file, the data may be correctly received. WebApr 7, 2024 · indeed, the uhd_packet_rx.grc flow graph has two different sync elements: 1. the FLL band-edge 2. PFB Clock Sync within the packet_rx hier block, as you've noticed. In your case, it's possible the FLL doesn't attack fast enough; you would verify that by comparing waterfalls / spectra of the signal before and after.

WebJan 21, 2024 · It says that the packet_loopback example is a transceiver, and I can replace the Channel Model blocks with USRP source and USRP sink blocks to try to send a message over the air. I did that, but I'm running into overruns and underrruns and want to know how to fix that. Thanks everybody for speedy replies and the help so far! It's much appreciated!!
