Ahmed Hussein 10e3a299be Restructuring "nr_slot_fep_ul" 
- Now it takes input and output pointers instead of gNB struct
 2019-06-04 13:43:20 +02:00
Ahmed Hussein 02e329a35d SC-FDMA working for 1 SNR loop (enabled using "NR_SC_FDMA" MACRO) 
- Added nr_dft at UE side and nr_idft at gNB side
- NR_SC_FDMA can be found in "PHY/defs_nr_common.h"
- For 1 SNR loop, the code executes correctly
- For more loops, it gives a segmentation fault in the LDPC decoder
- The segmentation fault is caused when nr_idft is used
- The code works fine when the "NR_SC_FDMA" is disabled

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

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.

Florian Kaltenberger 83e9908adb merging develop with develop-nr 2018-10-25 03:15:09 -07:00
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)
