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.
Applications
  • 5G-NR 3GPP Rel.15 modem chipset for base station (BS) or user equipment (UE)
  • Applications with 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, decoding success, number of modified bits)
  • Available for ASIC and FPGAs (Xilinx, Intel/Altera)
  • Deliverable includes VHDL source code or synthesized netlist, VHDL or SystemC testbench, and bit-accurate Matlab, C or C++ simulation model
