Encoder and Decoder 

The recommended CCSDS 131.2-B-1 standard introduces a Serial Concatenated Convolutional Code (SCCC). Main goal of this code is to allow an efficient use of available bandwidth, by allowing to select from 27 valid configurations with a wide range of constellations, block lengths and code rates.

The outstanding error correction performance of the SCCC code in combination with the high data rates makes this IP core the ideal fit for further applications where high throughput and high spectral efficiency is key for operation.
