DVB-S2X Wideband LDPC/ BCH Decoder

Overview

The Creonic DVB-S2X wideband decoder is a scalable solution that allows for symbol rates of up to 500 MSymb/s on state-of-the-art FPGAs

Key Features

  • Compliant with DVB-S2 and DVB-S2X
  • Support for decoding of BBFRAMEs
  • Support for ACM, CCM, and VCM
  • Support for short and normal frames (16 200 bits and 64 800 bits)
  • Support for QPSK, 8-PSK, 16-APSK, 32-APSK, 64-APSK, 128-APSK, and 256-APSK

Benefits

  • Validated against 3rd party DVB-S2X modulators.
  • Based on industry-proven design for DVB-S2.
  • Soft-Decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler included.
  • Low-power and low-complexity design.
  • Frame-to-frame 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 with on-the-fly selection in ACM/VCM modes.
  • Collection of statistics (error rates, average number of iterations, signal-to-noise ratio (SNR)).
  • Available for ASIC and FPGAs (Xilinx, Intel).
