TC1000-WiMAX: 802.16 d/e CTC

TurboConcept LogoTC1000-WiMAX is a Convolutional Turbo Code (CTC) decoder optimized for IEEE 802.16 d/e applications. It offers near floating point Bit Error Rate (BER) for all block sizes and modulations. The Core implementation achieves unmatched complexity/throughput performance, thanks to a high speed parallel processing architecture. Three throughput levels are proposed (“2X”, “4X” and “8X”), ranging typically from 50 to 200 Mbits/s decoded at 5 iterations (depending on the target device). The functional support can be adapted to the system needs before Core synthesis by selecting the maximum block size (between 60 and 600 bytes).


  • Covers IEEE802.16d-2004 (fixed), IEEE802.16e-2005 (mobile)
  • Supports all block sizes, including the block sizes for H-ARQ operation
  • Three throughput levels available ("2X","4X" or "8X"), 50 to 200 Mbps at 5 iterations
  • Early iteration stopping feature
    • Reduces power consuption
    • Increases average throughput by + 60%
  • Advanced architecture - low complexity
  • Selectable quantization width - 3 to 8 bits
  • On-the-fly (Block-by-block) change of code rate, block size, number of iterations
  • Latency reduction by bank-swapping (2 input buffers)
  • In-operation BER monitoring
  • Micro-controller interface
  • Encoder Core included
  • Includes depuncturing and sub-block deinterleaver
