5G-NR LDPC Decoder and Encoder


5G NR is the mobile broadband standard of the 5th generation. A new rate compatible structure for LDPC codes are employed for channel coding to fulfill the broad applications supported by the standard. Creonic’s 5G LDPC Decoder and Encoder IP cores provide a perfect solution for this new LDPC structure with high level of flexibility while maintaining high throughput and low latency as required by the standard.

Applications




  • 5G modem chipset for base stations
    (BS) or user equipment (UE)

  • Applications with the highest demands on forward error correction
  • Applications with the need for a wide range of code rates and block length

Standard Features the Core Supports


  • Support for 3GPP Release 15 5G
    LDPC decoding

  • Support for base code rates from
    22/68 to 22/26 for basegraph 1

  • Support for base code rates from
    10/52 to 10/14 for basegraph 2
  • Depuncturing and puncturing is included in the cores


      

   Your Benefits


      

  • High-throughput design
  • Low-power and low-complexity design
  • Block-to-block on-the-fly configuration
  • AXI4-Stream handshaking interfaces for seamless integration
  • 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
  • Collection of statistics (decoding success, iterations needed)
  • Available for ASIC and FPGAs (AMD Xilinx, Intel)
