5G-NR LDPC Decoder

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 IP Core provides 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.







  • 5G-NR 3GPP Rel.15 modem chipset for base station (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 5G-NR 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
  • Compliant with 3GPP Release 15


   Your Benefits


  • High throughput
  • 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 (number of iterations, decodingsuccess, number of modified bits)

  • Available for ASIC and FPGAs (Xilinx, Intel/Altera)

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