[srslte-users] Accessing RX Sample Buffers in MIMO

[Nick Smith]

Hi all,

I was trying to modify the code in srsenb (v.20.10.1) to allow me to access
the raw sample buffers of the two receiving antennas in a 2x2 MIMO scheme
(tm=4, nof_ports=2). I've tried tracing the process from the radio to the
subframe workers, and it seems like I'd only need to call
cc_workers[cc]->get_buffer_rx(antenna_index)
for antennas 0 and 1 in sf_worker.cc before the uplink is processed.
However, whenever I try this, it keeps giving me Segmentation Fault errors.
Is there a better way to do this? I saw where the first antenna's sample
buffer is stored in enb_ul.ofdm_cfg.in_buffer but I couldn't find the
second.

Thank you,
Nick
