Inner coder with Puncturing.
ETSI EN 300 744 Clause 4.3.3
Mother convolutional code with rate 1/2. k=1, n=2, K=6. Generator polynomial G1=171(OCT), G2=133(OCT). Punctured to obtain rates of 2/3, 3/4, 5/6, 7/8.
Data Input format: Packed bytes (each bit is data). MSB - first, LSB last.
- Data Output format
- 000000X0X1 - QPSK.
- 0000X0X1X2X3 - 16QAM.
- 00X0X1X2X3X4X5 - 64QAM.
Parameters[edit]
- Input length
- length of input.
- Output length

- Constellation type
- type of constellation.
- Hierarchy type
- type of hierarchy used.
- Code rate
- Code rate used.
