Raymond Knopp 58f1dd5e49 debugging of DCI reception up to extraction of DCI fields in UE.

Raymond Knopp e7c63993d6 changed name of function initial pdcch scheduling parameters. Currently we set the BWP information to be the full bandwidth of the NR cell. This should be changed to include the CellGroupConfigCommon initial BWP information either from SIB or from LTE RRC. 
DCI still not updated to start from MSB. Will be in next commit

dci encoding / decoding integrated
DCI decoding still fails

Raymond Knopp 5c2a411a5b added optimized polar decoding to UE DCI processing. Still to be tested. Changed decoder API to return XOR(CRC,rxCRC) which can be used to check for RNTI at receiver. For PBCH it returns 0 on positive CRC, !=0 on CRC mismatch. 2018-11-11 12:24:26 +01:00

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.

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)
