[srslte-users] Frequency offsets in srsUE

Hello Philip:

Are you basically asking how to do offset tuning with srsRAN/srsLTE/srsUE?
I'm not sure whether this is currently supported.  You should be able to
have srsUE tune to a non-3GPP frequency band (which is basically the effect
of using offset tuning), but I'm not sure that the srsUE PHY would be able
to accommodate for that in its processing.

Hi Neel / Paul,
I have a X300 with a UBX160.  I need to move the analogue BB signal away from DC zero Hz before it enters the X300 for ADC etc.  I can set an offset using the property in the config file.  I can see that the search for a cell is now at this offset frequency (at the analogue signal point on the interface between the UBX160 and X300).  I don't have a cell to connect to (for testing), so the question is will srsUE connect to a cell using a large offset value?

A offset of 1Mhz would be perfect for what we are doing.  Will the PHY work?  So, the system knows that the received signal is offset from zero Hz and is able to recover it?

Thank you.

Philip
