DVB-S2X LDPC/BCH Decoder

DVB-S2X is the next generation satellite transmission standard that extends its well-established predecessor DVB-S2. The new specification allows for spectral efficiency gains of up to 50% by offering lower roll-off factors, higher modulations and a finer code rate granularity compared to DVB-S2. The Creonic DVB-S2X decoder is a scalable solution that allows for symbol rates of up to 100 MSymb/s on state-of-the-art FPGAs.

特色

Compliant with ETSI 302 307 V1.2.1 (2009-08) (DVB-S2) and DVB-S2X.
Supports ACM, CCM, and VCM modes.
Support for short, medium and long blocks (16200, 32400 and 64800 bits).
Support for all modulation schemes (BPSK, QPSK, 8-PSK, 16-APSK, 32-APSK, 64-APSK, 128-APSK, 256-APSK).
Support for very low SNR modes (VLSNR) with SNRs below -9 dB.
Support for all LDPC and BCH codes as defined by the standard.

优势

Based on industry-proven design for DVB-S2.
Decoder contains soft-decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler.
Low-power and low-complexity design.
Burst-to-burst on-the-fly configuration.
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 statistics (decoding success indicator, average number of iterations).
Available for ASIC and FPGAs (Xilinx, Intel).

可交付内容

Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model.
