[srsran-users] 回复： srsRAN:Can bladeRF 2.0 micro xA4 be used in 5G network?

[Zishuai Cheng]

Hey Adam,

Not sure if your SDR is running on USB 3.0. For the Overflow, I do have 
several suggestions. Most of them are included in srsRAN docs.

 1. Try to use USB3.0 instead of USB 2.0;
 2. Let the host run on performance mode;
 3. If testing with LTE, try to reduce the n_prb. Since you are testing
    5G, you may can skip this step;
 4. Try an another powerful computer, I remember the srsRAN docs have
    suggestions about the CPU;
 5. Try to configure the host to use real-time kernel. To be honest, I
    haven't tried this because a more powerful computer has solved the
    overflow problem on my side.

Hope these suggestions could give you some intuition.
