DVB-C2 Receiver (including LDPC and BCH decoder)

DVB-C2 (Digital Video Broadcast – Cable 2nd Generation) is an ETSI standard of the second generation for digital data transmission via cable networks. It complements the existing standards DVB-S2 and DVB-T2 for satellite and terrestrial communication and offers a capacity-approaching coding scheme. The Creonic DVB-C2 IP core integrates the forward error correction as defined by the standard (including LDPC and BCH decoder).

• Compliant with ETSI 302 769 V1.2.1 (2011-04) (DVB-C2)
• Support for short and long blocks (16,200 bits and 64,800 bits)
• Support for decoding of L1 signalling part 2 data
• Support for all modulation schemes (16-QAM, 64-QAM, 256-QAM, 1024-QAM, 4096-QAM)
• Support for all interleaving schemes of all modulation schemes
• Support for all LDPC and BCH codes as defined by the standard

• Soft-Decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler included
• Based on industry-proven design for DVB-S2
• Low-power and low-complexity design
• Burst-to-burst on-the-fly configuration
• Design-time configuration of throughput for optimal resource utilization
• Faster convergence due to layered LDPC decoder architecture
• Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy
• Configurable amount of LDPC decoding iterations for trading-off throughput and error correction performance
• Collection of statistic information (number of modified information bits, number of iterations, etc)
• Available for ASIC and FPGAs (AMD Xilinx, Intel)
• Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model
• The software model includes the corresponding transmitter part

• Digital Video Broadcasting in cable networks
• Further applications with highest demands on forward error correction
• Applications with high signal-to noise ratios
• Applications with the need for high code rates (2/3 to 9/10)

• VHDL source code or synthesized netlist
