DOCSIS 3.1 LDPC FEC
Block Diagram
Overview
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial infrastructure. The Downstream (DS) NCP (Next Codeword Pointer) Decoder decodes NCP frames and there fore allows to convey plenty of information on the OFDM structure.
Features
- Parity deinterleaver, LDPC decoder,shortening unit, and BCH decoderincluded
- Support for all block sizes withshortening (3 to 1779 bytes payload)
- Support for data rates of more than2.3 Gbit/s
- Soft-Decision demapper,derandomizer, deinterleaver,depuncturing unit, and LDPC decoderincluded
- Support for 16-QAM modulation & Support for 4k and 8k FFT size
