  • Block Diagram -- BCH Encoder and Decoder IP Core
  • DVB-S2 LDPC BCH Decoder and Encoder
    • The DVB-S2 LDPC-BCH block is a powerful FEC (Forward Error Correction) subsystem for Digital Video Broadcasting via Satellite.
    • In Digital video broadcasting for digital transmission for satellite applications, a powerful FEC sub-system is needed. FEC is based on LDPC (Low Density Parity Check) codes concatenated with BCH (Bose Chaudhuri Hocquenghem) codes, allowing Quasi Error Free operation close to the Shannon limit.
  • BCH encoder and decoder for NAND FLASH
    • Parameter customizable
    • AXI interface, easy integration
    • High throughput with low complexity hardware
  • DVB-S2 BCH and LDPC Encoder and Decoder
    • Compliant with ETSI 302 307 V1.2.1 (2009-08) (DVB-S2).
    • Support for short blocks (16200 bits) and long blocks (64800 bits).
    • Support for all modulation schemes (QPSK, 8-PSK, 16-APSK, 32-APSK).
    • Support for all interleaving schemes of all modulation schemes.
  • Block Diagram -- FSK Demodulator,BCH Decoder,Command Decoder,Validator,Convolution Encoder IPs
  • NR-5G Polar Encoder /Decoder
    • The NR-5G Polar encoder/decoder is developed for 5G new radio.
    • Fully compliant with 3GPP TS 38.212  Sections 5.2.1, 5.3.1, 5.4.1 and 5.5
  • BCH Intel® FPGA IP Core
    • The Bose, Chaudhuri, and Hocquenghem (BCH) error correction intellectual property (IP) core is typically used in NAND flash applications
    • The BCH Intel FPGA IP core is often used as a companion code with other forward error correction (FEC) IP cores, such as the Reed-Solomon and low-density parity-check (LDPC) IP cores.
  • BCH Encoder/Decoder
    • High-speed encoder and decoder
    • Codeword length 1023 bits
    • 903 information bits in the codeword
    • Maximum number of error bits that can be corrected =12
  • DVB-T2 Rx Bit Chain
    • Short and Long Frames
    • SISO
    • Flexible channel BW (1.7, 5, 6, 7, 8, and 10) MHz
    • Flexible modulation (QPSK, 16QAM, 64QAM, and 256QAM)
    • Flexible FFT size (1, 2, 4, 8, 16, and 32) K
    • Flexible guard interval (1/128, 1/32, 1/16, 19/256, 1/8, 19/128, and 1/4)
