    WiMAX IEEE802.16e LDPC decoder

    Product code: TC4200

    TC4200-WiMAX Core is a high speed Low Density Parity Check code (LDPC) decoder optimized for WiMAX (IEEE 802.16e) specifications. A patented decoding architecture allows meeting high throughputs within small devices, and still offering close-to-ideal Bit Error Rate (BER) performances. Two core versions are available (*):

    • a 75 Mbps decoded bitrate
    • a 150-200 Mbps decoded bitrate
    (*) Throughput depends on the selected device and vary with the block size. Please contact us for additional information.

    Functional coverage:

    Covers all LDPC options specified in IEEE802.16e-2005 (mobile):
    • block sizes: 576 to 2304 coded bits
    • code rates 1/2, 2/,3 3/4, 5/6


    • Two throughput levels available: 75 and 150-200 decoded Mbits/s
    • Near floating point bit error rate (BER) performance
    • Early iteration stopping feature
    • Patented architecture allowing high throughput for reduced footprint
    • On-the-fly (block-by-block) change of code rate, block size, number of iterations
    • Low latency
    • Single FPGA Core, available on popular Xilinx, Altera and Lattice devices
    • ASIC Core: Verilog or VHDL RTL Core
