【简　介】:Abstract—This letter is concerned with the implementation issue
of the sum-product algorithm (SPA) for decoding the low density
parity check codes. It is shown that the direct implementation of the
original form of SPA is sensitive to the quantization effect.We propose
a parity likelihood ratio technique to overcome the problem.
It is shown that for comparable performance the new method can
be implemented with much less quantization bits, which can lead
to considerably lower decoding cost.
Index Terms—Error correcting codes, low density parity check
codes, turbo codes.
