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).

Features

  • 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
