altaf sk altaf329 at gmail.comHelo I am working with the LTE_FDD_DL_SCAN application which is running with a USRP B210 connected via USB3. The application works with flowgraph and connected to USRP source through gr-osmosdr. Running with a Sampling rate: 15.36MS/s Master clock rate: 15.36MS/s using gnuradio 3.7.3 and uhd 3.7.1 causes the overrun 'o' printed on stdout every 3-4 seconds. This problem is not seen when running over sampling rates less than 8MS/s. The signal processing function on the host has heavy computing and I do not want to change the decimation factor. I tried running the application with high priority but no success. Is it possible to solve with recv_buff_size parameter.? Does gr-osmosdr have any function (implemented) that can increase the buffer size. Can you suggest other ways to boost the speed and control overruns.
