[srslte-users] SrsLTE using USRP N321

[Charbel Lahoud]

Hello,

I have successfully build srsLTE software with radio heads USRP N321. But it is only working with 75 resource blocks, when I change to other options such as 100, 50 and 25 the srsue isn't connecting and I have additional warnings.

[WARNING] [RFNOC] The requested decimation is odd; the user should expect passband CIC rolloff.
Select an even decimation to ensure that a halfband filter is enabled.
Decimations factorable by 4 will enable 2 halfbands, those factorable by 8 will enable 3 halfbands.
decimation = dsp_rate/samp_rate -> 11 = (245.760000 MHz)/(23.040000 MHz)

[WARNING] [MULTI_USRP] The hardware does not support the requested RX sample rate:
Target sample rate: 23.040000 MSps
Actual sample rate: 22.341818 MSps
