On decoding methods beyond the BCH bound and their applications to soft-decision decoding
Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1999For the two-dimensional BCH code, several decoding methods exceeding the BCH bound and correcting the errors that cannot be corrected by the conventional limited distance decoding method have been proposed. This article proposes an algorithm that allows reduction of the computational volume in a decoding method exceeding the BCH bound by solving the ...

On decoding methods for double‐encoding systems [PDF]
Electronics and Communications in Japan (Part I: Communications), 1982 AbstractDouble encoding is a method by which a new code is constructed by twofold encoding with two codes. Using this method, a code with excellent error‐correcting capabilities can be constructed from relatively simple codes. The decoding can also be made simpler compared with a single code with the same code length and the same error‐correcting ...

A fast decoding method for prefix codes
Data Compression Conference, 2003. Proceedings. DCC 2003, 2003Summary form only given. Prefix codes allow text to be decoded without ambiguity, since this code is a variable-length type where no codeword is a prefix of the other. The problem of improving the decoding speed has received special attention in the data compression community.

On the capability of (T, U) permutation decoding method
IEEE Transactions on Communications, 1994Error-trapping decoding techniques are attractive due to their simple structure. Since 1962 several improved error-trapping methods have been devised in an effort to extend the capability and effectiveness in decoding multiple-error-correcting cyclic codes. Prange (1962) and MacWilliams (1964) introduced a (T, U) permutation group applied to this error-

An efficient decoding method of sequence-pair
Asia-Pacific Conference on Circuits and Systems, 2003The sequence-pair was proposed as a representation method of block placement to determine the densest possible placement of rectangular modules in VLSI layout design. In this paper, we propose a method of obtaining packing via the Q-sequence (representation of rectangular dissection) in O(n+k) time from a given sequence-pair of n rectangles with k ...

Methods and limits of iterative multiuser decoding
Proceedings 2001 IEEE Information Theory Workshop (Cat. No.01EX494), 2002Previous work has identified iterative multiuser decoding techniques that are often only limited by theoretical channel capacity. These investigations usually dealt with the case where user waveforms are decorrelated to some degree. Investigations with identical waveforms indicate that the theoretical capacity limits are not always achieved ...

Method And Apparatus To Decode Audio Matrix
The Journal of the Acoustical Society of America, 2011A method of audio matrix decoding in which a moving sound image is restored includes decoding multichannel signals from stereo signals, extracting strengths and positions of virtual sound sources existing between channels based on power vectors of the decoded multichannel signals, comparing the strengths and positions of the extracted previous and ...

A Method for Reducing the Complexity of Meggitt Decoder
2018The decoding principle of linear block code is based on the syndrome which determines the error location of the received codeword. When considering the Hamming code, there will be eight syndromes with eight decoding circuits when there is one bit error. Cyclic code is a special case of linear block codes which is still a cyclic code after cyclic shift.
