- Channel coding (Turbo coding)
- Rate matching (sub-block interleaving, bit collection, selection and transmission
- Code block concatenation

\brief This function performs a subset of the bit-coding functions for LTE as described in 36-212, Release 8.Support is limited to turbo-coded channels (DLSCH/ULSCH). This version spawns 1 worker thread. The implemented functions are:
- CRC computation and addition
- Code block segmentation and sub-block CRC addition
- Channel coding (Turbo coding)
- Rate matching (sub-block interleaving, bit collection, selection and transmission
- Code block concatenation
