[srsran-users] How to set the sampling rate according to your need?

[家祺 张]

Hi everyone,



I'm running srsRAN to monitor a commercial base station with bandwidth 20MHz to get some physical signal information.

But I find that maybe my computer cannot support real-time processing of such high bandwidth, so I tried to use a custom

sample rate instead of the default sample rate.



For example, for 20MHz bandwidth signal, I want to use sample rate 15.36MHz to only use 10MHz bandwidth signal. How I can do this?

Do I only need to set the parameter srate=15.36e6 in ue.config? I’v tried this way, but get some errors like SYNC：Found PSS

but could not decode PBCH. Does this mean that the sample rate must be matched to the signal bandwidth? Then, what is

the point of setting parameter srate?



Could you please give me a hand ? There's really nothing more I can do about this kind of problem, thank you very much

for your kindness in taking a little time to focus on it.


Thanks sincerely,



Eric
