| description | This paper describes the implementation of a general
and embedded decoder for the evaluation of unstructured
low-density parity-check (LDPC) codes over additive-white Gaussian
noise (AWGN) channels. The decoder, which has a serial architecture
and moderate throughput, is a peripheral connected to
the embedded PowerPC processor of a Xilinx Virtex-II Pro FPGA
and is managed by the processor. This method of Hardware/
Software implementation provides the maximum flexibility for
the development and rapid prototyping of the hardware-based
simulator system. The decoding algorithm proposed in this paper
belongs to the class of min-sum with correction factor in which
the correction factor updates with the log-likelihood ratio (LLR)
values. |
