T2 card: LDPC encoder/decoder TB processing
Not ready for review yet, testing is ongoing
- offload of the LDPC decoding/encoding on the gNB side tested with 1 and multiple UEs (Quectel modules), results similar to develop
- offload of the LDPC decoding/encoding on the UE side to be tested
RAN-gNB-N300-Timing-Phytest-LDPC results
- LDPC decoder, processing time based on nr_ulsim
