Unicore Systems 
Short Desc. : IEEE 802.16e (WiMAX) and IEEE 802.11n (WiFi) LDPC Decoder IP core
Overview :
Error-correcting coding is an essential tool for enabling reliable communication. Unicore Systems provide an Intellectual Property (IP) core for hardware-efficient implementation of low-density parity-check (LDPC) forward error correcting (FEC) schemes intended for the IEEE 802.16e and for the 802.11n. The IP core covers the entire WiMaX and WiFi LDPC specification, in
terms of block size and code rate.WiFi mode,WiMax mode, block size and code rate can be switched on a block-by-block basis.
Features : - WiMax 19 code length supported (Z factor 24,28...96);
- WiFi 3 code length supported (Z factor 27,54,81);
- WiMax all code rates 1/2, 2/3A, 2/3B, 3/4A, 3/4B, 5/6 supported;
- WiFi all code rates 1/2, 2/3, 3/4, 5/6 supported;
- parameterized input data width 5-8 bit (in compilation phase);
- parameterized internal data width 6-9 bit (in compilation phase);
- nearly floating point performance with quantization of 5 input bits and internal computation in 8 bits (less then 0.15 dB from floating point BP with 30 iterations);
- early stop detection unit ;
- parallelism degree 96;
- bit-LLR input
- decoded throughput up to 193 Mbit/sec (Virtex-4 -12 speed grade) for WiMax mode. (Z=96, 15 iterations, Fclk=160 MHz)
- decoded throughput up to 164 Mbit/sec (Virtex-4 -12 speed grade) for WiFi mode. (Z=81, 15 iterations, Fclk=160 MHz)
- Free LDPC Encoder IP core comes with the Decoder
