LDPC Encoder / Decoder Compatible with the IEEE 802.16e WiMax

SiliconPro’s SP2200 is a high performance Forward Error Correction (FEC) IP core compatible with the IEEE 802.16e WiMax standards. The SP2200 is LDPC based encoder/decoder that supports all the code rates in the WiMax standard. It can also support the different code lengths, from 576 bits to 2304 bits. The SP2200 can be reconfigured in real time for a wide variety of block sizes, code rates, and number of iterations, which make it suitable for a wide range of channel characteristics.
