HINOC (High performance Network Over Coax) technology is a broadband access technology based on coaxial cable, it’s born for the tri-networks integration of our country. HINOC system is based on OFDM technology, which is easy to be affected by single-frequency interference.This topic concerns the BCH coding algorithm and its hardware implementation which is applied in

With the development of modern digital communication, LDPC codes attract much attention from both industry and academic society because its excellent error correction capability. On the other hand, lots of research work has been devoted to Non-binary LDPC codes. This paper concentrates on the design of LDPC decoders for various digital communication standards and the

Along with the development of statistical machine translation (SMT), we have witnessed the model of SMT’s has experienced periods of word model, phrases model, formal syntax model, tree-to-string model string-to-tree model. At present some scholars are even trying to build a tree–to-tree model. So many complicated models there are, and such a variety of decoders

Low Density Parity Check (LDPC) codes are a class of capacity approaching error correcting codes of which the decoding performance can get near Shannon limit. For long code length, LDPC codes can even outperform Turbo codes. Based on belief propagation, the complexity of decoding algorithms is very low. Due to these advantages, the application of

Compared with the DVB-S standard, the DVB-S2 standard (The Second Generation Of Digital Video Broadcasting For Satellite Application) has greatly improved, the modulation is promoted to 16APSK, 32APSK from 8PSK, performance is greatly improved by adaptive coded modulation and the Error-correcting capability achieves about 3dB improvement. The reason why DVB-S2 has a better performance is

The channel coding is an important component in optical fiber communication systems. As a new type error correcting code of forward error correction (FEC) technology, Turbo product codes (TPC) has good capability of error correction which is close to the Shannon limit.And TPC has become a hot topic in the channel coding area.Up to now,
