[USRP-users] nr-softmodem run error
Dear All, I’ve successfully built uhd and other dependencies, by executing this command: `sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.conf --sa -E --continuous-tx`. I got following error: nr-softmodem: /usr/include/boost/smart_ptr/shared_ptr.hpp:734: typename boost::detail::sp_member_access::type boost::shared_ptr::operator->() const \[with T = uhd::property_tree; typename boost::detail::sp_member_access::type = uhd::property_tree\*\]: Assertion \`px != 0' failed.

[USRP-users] Re: nr-softmodem run error
Hi! This is incredibly hard to debug with this little info, but the most likely case would still be an API mismatch between the version of Boost or UHD that you use for NR-Softmodem and for your UHD build. Make sure you don't have multiple, potentially conflicting versions of UHD or Boost installed. Best regards, Marcus DISCLAIMER: Any attached Code is provided As Is.

[USRP-users] Decreasing Power at Higher Frequencies
Hello, I design a system on GNU Radio with USRP and coded it in Python. I am hopping frequency. Then I restart this process. I save all max. value at different frequencies. I am sharing datas with you. All data you can see in this document I take connection with cable. I mean I connect TX port to RX port with cable. I know possible dangers. My problem is I expect all datas are same even they don’t be same frequencies. I would not expect the dB difference between 100MHz and 6Ghz almost 40dB. Another problem is Even though I dont change the position of anything (Because I connect with cable) I take different values at replays. With the cable the difference is almost 3dB. But if I connect with antennas the difference at some frequencies is maybe 15dB even I don’t change the position of antennas. If I stabilize this, I change position of antennas dynamically. I will be glad if you help. data.xlsx Description: Zip archive ___ USRP-users mailing list -- usrp-users@lists.ettus.com To unsubscribe send an email to usrp-users-le...@lists.ettus.com
