Sakthivel Velumani 334519d16a Fixed several bugs in UE initial sync procedures 
Now UE gets sync all time in rfsimulator. Yet to be tested with hardware.

Francesco Mani 385dcea7eb intial sync over two frames (not working, still need to debug) 2019-04-03 15:07:45 +02:00
Florian Kaltenberger 6db55b2f24 - UE channel estimation no longer done in slot_fep. Also created dedicated memory for channel estimates of different channels 
- using nr_extract_dci_info instead of nr_generate_ue_ul_dlsch_params_from_dci as in phy_procedures_nr_ue. The latter was only a (poor) wrapper and not doing what the name suggests. also with FAPI things have to be done differently now. This will come in a next commit.
- other minor changes to remove warning

 2018-11-01 16:50:41 +01:00
Florian Kaltenberger a17ccf0646 adding N_RB_DL to nr_init_params, as it is needed in the gNB and the function is shared between gNB and UE. This should be revisited. 2018-10-28 13:09:12 -07:00
Raymond Knopp d7c71252f0 nr_pbchsim: added -I option which runs initial synchronization. without, it just runs pbch decoding 
Still a remaining issue with the SNR normalization, way too low to get errors.
 2018-10-25 22:50:35 +02:00
Raymond Knopp 8d78c0c98f Changes: 
0. unwiring of 40 MHz channel hard-coding and general SSB location
1. PSS dynamic range improvement and DC carrier fix
2. SSS channel estimation and detection corrected
3. PBCH channel estimation fixed
4. PBCH channel extraction/compensation reworked for the general case
5. fixed-point low-complexity polar decoder integrated to PBCH decoding chain

works by default (nr_pbchsim) at 100 MHz / 30 kHz SCS and SSB wherever (but known to UE)
