TC1700: Turbo decoder Core for HSPA+, LTE & WiMAX

TurboConcept LogoTC1700 is a turbo decoder that supports three PHY layer specifications:

  • 3GPP-LTE
  • WiMAX IEEE802.16e

The Core can be implemented in Base station or CPE receivers. The Core uses a unique architecture that reduces by more than 50 % the silicon area when compared to separate single-mode Cores, with no restrictions on the flexibility and features set. The Core is based on our robust and silicon-proven architecture that has been adopted by leading 4G system-on-chip manufacturers. The corresponding encoder Cores are also available with similar functional coverage.


  • Full coverage of 3GPP-HSPA+
    • block sizes range: 40 to 5114 bits
    • rate-matching
  • Full coverage of 3GPP LTE specifications
    • block sizes range: 40 to 6144 bits
    • rate matching: support of depuncturing, sub-block deinterleaving
    • CRC decoding
  • Full coverage of IEEE802.16d/e WiMAX specifications
    • maximum block size: 60 or 600 bytes (selectable)
    • depuncturing, sub-block deinterleaving
  • Block-by-block change of physical layer mode (HSPA+/LTE/WiMAX), block length, and number of iterations
  • Throughput up to 500 Mbps decoded with 4 iterations (please contact us for device-specific figures)
  • Dynamic stopping capability for reducing average number of iterations
  • Latency reduction by bank swapping
  • No external memory required
  • Channel BER estimator
  • Selectable quantization level - prior synthesis (4 to 8 bits LLR quantization)
  • Low power Core
