Transport Channel Subcomponents

CRC coding, code block segmentation, polar and LDPC coding, rate matching and recovery in 5G NR

Use 5G Toolbox™ low-level transport channel subcomponent functions to:

  • Perform cyclic redundancy check (CRC) encoding and decoding.

  • Perform polar encoding, decoding, rate matching, and rate recovery.

  • Perform low-density parity-check (LDPC) encoding, decoding, rate matching, and rate recovery.

  • Perform LDPC code block segmentation and desegmentation.
