Short Desc. : LDPC decoder for 802.16e - WiMAX
Overview :
An optimized hardware-efficient core for implementation
of the standard supported LDPC coding is
described. The proposed solution has essential performance
and implementation advantages over existing convolutional
and turbo-convolutional schemes.
Features : - Support all codes defined in the standard: 1/2, 2/3A, 2/3B, 3/4A, 3/4B, 5/6.
- Support all 19 codes lengths, from 576 to 2304 bits.
- Programmable number of iterations.
- Internal convergence test stops the decoder when data is fully recovered (0 errors).
- Decoded data rate exceeds 12-20 Mb/s (rate depended) with 10 iterations using 1 PU at 200-MHz clock frequency.
- Code synthesizable to ASIC and FPGA.
