[srslte-users] DL stream in srsUE

[Mathias Rønholt Kielgast]

Hi again,

I would much appreciate some help on this subject, though it may be a stupid question?
I had hoped to be able to output the I/Q samples at some point in the radio layer (writing to some log_file), however, it does not seem that DL data is parsed through the radio module at all?
Instead, I'm lost somewhere between the physical channel recv and worker. Are there not some point where all uplink data is parsed through, independently on sync status and so on? Because it seems like the DL is fractioned between different function calls parsing some reference to a buffer with it?

Yours sincerely,

Subject: DL stream in srsUE

Hi,

I would like to make some "recordings" of the DL stream that goes into srsUE. However, I have difficulties tracking the input data is transferred to the PHY layer from the UHD driver (I am using an USRP B210), as it seems the processing is occurring through some of the many structs applied in the physical channel worker?
Where is the downlink stream parsed to the physical layer? If I want to "record it", where could I do that?

Yours sincerely,
