Raymond Knopp df8b32b8ea fast polar encoder functional only for 32-64 bit input (B, payload+crc) 2018-10-28 14:14:58 +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.

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)
