Abstract [en]

Data representations for LDPC decoders using the sum-product algorithm in the log-likelihood domain are considered. It is suggested that the look-up table implementation of the domain transform function is separated into two parts, allowing a compact representation of the internal state data. Memories and bus widths can be reduced by typically 16\%, while the imposed hardware overhead is insignificant.
