Raymond Knopp fb65ca001a Merge remote-tracking branch 'origin/develop-nr' into nr-polar-encoder-optimizations 2018-11-11 12:26:27 +01:00
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

Florian Kaltenberger eb484b8039 changing n_ssb_crb to n_rb_dl-20 re-centers the SSB and PDCCH and UE can decode PDCCH again 2018-11-07 15:16:01 +01:00

Raymond Knopp 123f874561 addition of initialization of first two polar encoder tables (up to rate matching) 2018-10-26 08:33:25 +02:00
Raymond Knopp 7d03e935a6 added crcmask and removed some warnings 2018-10-26 01:57:02 +02:00
Raymond Knopp c5c3c325f0 added all optimizations except rate matching for N=512 polar-encoder. 2018-10-26 01:40:31 +02:00
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)
