5G-NR Compliant Polar Decoder

Polar codes are capacity-approaching codes for the small block lengths, and therefore, are chosen for the 5G-NR control channels. This IP core implements an optimized Polar decoder that is compliant with 5G-NR Polar decoding, 3GPP release 15. 

 

The IP core:

  • implements simplified successive cancellation decoding,
  • supports code lengths of up to 512 bits,
  • significantly improves latency and throughput of the decoder by implementing radix-n F and G accelerators. 

 

Depending on your requirement, the IP-core deliverable may include:

  • System Verilog source code,

  • System Verilog testbench,

  • Synthesized netlist,

  • Matlab or C bit-accurate model for simulation. 

Test-implementation results:
  • Node : 65nm CMOS,
  • Peak Throughput : 825 Mbps,
  • Clock Frequency : 250 MHz,
  • Core Area: 0.326 mm2.
