Description: Abstract—In this letter, we propose an efficient decoding algorithm
for turbo product codes as introduced by Pyndiah. The proposed
decoder has no performance degradation and reduces the
complexity of the original decoder by an order of magnitude. We
concentrate on extended Bose–Chaudhuri–Hocquengem codes as
the constituent row and column codes because of their already low
implementation complexity. For these component codes, we observe
that the weight and reliability factors can be fixed, and that
there is no need for normalization. Furthermore, as opposed to
previous efficient decoders, the newly proposed decoder naturally
scales with a test-pattern parameter that can change as a function
of iteration number, i.e., the efficient Chase algorithm presented
here uses conventionally ordered test patterns, and the syndromes,
even parities, and extrinsic metrics are obtained with a minimum
number of operations. Platform: |

Description: A full-parallel architecture for turbo decoding, which achieves ultrahigh
data rates when using product codes as error correcting codes, is
proposed. This architecture is able to decode product codes using
binary BCH or m-ary Reed-Solomon component codes. The major
advantage of our architecture is that it enables the memory blocks
between all half-iterations to be removed. Moreover, the latency of the
turbo decoder is strongly reduced. The proposed architecture opens the
way to numerous applications such as optical transmission and data
storage. In particular, the block turbo decoding architecture can
support optical transmission at data rates above 10 Gbit=s. Platform: |

Description: 文章详细介绍了TPC编码技术及信道容限， 是一篇不错的介绍TPC的文章-An important goal for a new communication system is to transfer information at a high rate while
keeping energy consumption low. Shannon s channel capacity sets a limit on the tradeoff between the rate
of information transfer and the required energy. In this paper the performance of turbo block coding is
compared to Shannon s limit for binary communications over a channel with thermal noise. The turbo
product code is a relatively new code that offers a wide range of flexibility in terms of performance,
complexity, and code rate. The results of this paper will show that in comparison to a standard
convolutional code the turbo product code uses less power and permits a higher data rate for a given
bandwidth requirement. One of the turbo product codes discussed in this paper has a rate approximately
0.8, which is a 60 improvement in data rate over the standard convolutional code. It is also shown that
the performance of the turbo product code is close to Shannon s capacity limit Platform: |
