2020 International Conference on Artificial Intelligence in Information and Communication (ICAIIC), 2020 We consider a concatenated coding scheme which consists of the tail-biting convolutional code as an inner code and the hamming code as an outer code. They are separated by a block interleaver. The size of the row of the block interleaver is fixed to the length of the codeword of the hamming code. We select the interleaving depth, the size of the column

Concatenated Error Correction Code Implementation on FPGA
2019 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO), 2019 The requirements of highly reliable data transmission over interference and noisy channels are imposed on modern radio communication systems. In this connection, forward error correction has become an indispensable step in the digital processing of information data during transmission.

Iterative decoding for concatenated error correction coding in PRML channel systems
Seamless Interconnection for Universal Services. Global Telecommunications Conference. GLOBECOM'99. (Cat. No.99CH37042), 2003 A new iterative decoding scheme was developed for the cyclic redundancy check error correction code (CRCC), a concatenated error correction coding system. This simple iterative decoder achieves efficient cooperation between an outer Reed-Solomon error correction code (RS-ECC) decodes and a PRML trellis-detector.

Forward error correction concatenated code in DWDM systems
Frontiers of Optoelectronics in China, 2008 The three concatenated coding schemes of the inner-outer type, the parallel type and the consecutive type to improve the current forward error correction (FEC) coding technologies are proposed for dense wavelength-division multiplexing (DWDM) systems, after introducing the development trend of DWDM optical communication systems.

Concatenated code constructions for error correction in non-volatile memories
2012 International Symposium on Signals, Systems, and Electronics (ISSSE), 2012 This work investigates and compares different coding techniques for error correction in multilevel NAND flash memories. In particular, we consider strong error correction codes with an overall code rate of 0.8 and with a sector size of 1 kbyte. Two concatenated code constructions are compared to the state-of-the-art Bose-Chaudhuri-Hocquenghem (BCH ...

Soft Information Single Error Correction for Interactive Concatenated Codes
IEEE Transactions on Communications, 2012 This paper describes a concatenated code method where the outer decoder hypothesizes possible block symbol values for the inner code to make a likelihood retest from its original soft information. These hypotheses come from low density check sets where the probability is significant that there is only one error in the check set, whose value would be ...

Application of erasure error correction to concatenated partial-response channel code
1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003 Erasure error correction based on List-SOVA has been applied to partial-response channel code for high-density magnetic recording. Soft-output information extracted from modified EEPR4ML is used. To achieve as high a total coding rate as possible, a 16/17MTR(3;11) code and a rate 544/561 cyclic redundancy check code (CRCC) are combined.

The Influence of a Particular Error Pattern on the Error Correction Performance of RS+Convolutional Concatenated Code [PDF]
2017 International Conference on Computer Systems, Electronics and Control (ICCSEC), 2017 Our paper introduces a typical concatenated code, analyzes its performance about the error correcting capability and possible vulnerability. Moreover, an error pattern is proposed based on its coding structure. We also made a simulation to compare the influence to the decoding performance of concatenated code between the proposed error pattern and the ...

Maximal Length Burst Error Correction for Concatenated Packet/Vector Symbol Codes
IEEE Communications Letters, 2013 This letter shows how to extend packet/vector symbol burst error correction capability beyond prior known limits with the aid of soft information interaction with the inner code of a concatenated code. If the errors prove not to be in a burst, further correction still is possible with the aid of soft inner code information.

Journal of Central South University, 2017 This work investigates the performance of various forward error correction codes, by which the MIMO-OFDM system is deployed. To ensure fair investigation, the performance of four modulations, namely, binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM)-16 and QAM-64 with four error correction ...
