[srsran-users] Clarification on PUCCH and PDCCH Equalization Techniques in srsRAN

[Alin Stoica]

Hello,

I'm currently utilizing srsRAN for LTE network analysis and have been
closely examining the Uplink Control Channel (PUCCH) performance using
srsGUI. The visualized equalized symbols on the PUCCH have prompted some
questions regarding the underlying equalization techniques employed by
srsRAN.

I would appreciate if you could provide some details on the following:

   1.

   What equalization methods does srsRAN implement for PUCCH, and is it
   possible to choose between them, for instance, between Zero Forcing (ZF)
   and Minimum Mean Square Error (MMSE)?
   2.

   Moving on to the downlink, I'm interested in understanding how the
   Physical Downlink Control Channel (PDCCH) is processed. Is there a way to
   visualize PDCCH equalized symbols in srsGUI similar to PUCCH?

on UL traffic.
