TC7000-LTE: 3GPP-Long Term Evolution CTC Decoder

TurboConcept LogoTC7000-LTE is a convolutional turbo code (CTC) decoder optimized for 3GPP/LTE specifications. It offers several algorithm options to meet various trade-offs between error correction performance versus Core complexity. The decoder architecture is high-throughput oriented for all block sizes. Four throughput profiles are available, through parallel decoding architecture*:

  • 1 processor core :25 Mbps
  • 2-processors Core : 50 Mbps
  • 4-processors Core : 100 Mbps
  • 8-processors Core : 200 Mbps

* Throughput depends on the selected device and varies with the block size and number of iterations. Please contact TurboConcept for additional information.


  • Compliant with 3GPP-LTE
    • Block size covered from 40 to 6144 payload bits, switchable on the fly
    • Sub-block deinterleaver included.
    • CRC check included.
  • Near floating point error correction performance
  • High throughput Max-Log-MAP algorithm
  • Efficient and flexible optional Log-MAP algorithm
  • Multi-processor architecture, several throughput levels selectable before synthesis — from 25 to over 200 Mbps decoded
  • Optimal iteration stopping feature for reducing average number of iterations without performance degradation
  • On-the-fly change of block length and number of iterations
  • Low latency
