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)
