[srsran-users] eNB Warning - Could not set RX rate to 11.520 MHz. Actual rate is 11.703 MHz.

[Xavier Arteaga]

Hi Yufan,

The USRP you are using cannot derive 11.52MHz from 245.76MHz.

The standard DFT size and sampling rate are 1024 and 15.36MHz. However, the
DFT size is reduced to 768 which implies a sampling rate of 11.52MHz to
save some bandwidth by default. It is likely your device supports a
15.36MHz sampling rate.

You can force the enb to use the standard symbol size by recompiling
srsRAN_4G with the CMake argument -DUSE_LTE_RATES=On.

Kind regards,
Xavier
