Weighted erasure codec for the (24, 12) extended Golay code

TL;DR: In this article, an encoder and decoder are separated into two independent list decoders, a comparator, and common clock generator and output buffers, each list decoder is divided into a syndrome generator and an overall parity check generator, a syndrome error pattern table, an input buffer, error correction logic, and four-error detection logic.

Polynomial operator in galois fields and a digital signal processor comprising an operator of this type

TL;DR: The polynomial operator in the Galois field of the invention is organized at three levels: a multiplexer level to select and transmit the operands to be used for the successive stage of the calculation to a second level; a so-called pipeline level comprising 3 flip-flop registers to memorize the selected operands selected at the first level; and a third level for calculation, comprising a multiplier-adder which has its inputs X, Y and Z connected to the outputs of the registers, and which gives the coefficients of the resultant polynomials.

Table lookup direct decoder for double-error correcting (DEC) BCH codes using a pair of syndromes

TL;DR: In this paper, an approach for directly decoding and correcting double-bit random errors per word and detecting triple-bit error per word is presented. But this approach is not suitable for the decoding of large numbers of words.

Apparatus and method for a memory partial-write of error correcting encoded data

TL;DR: In this article, the error-correcting code check bits for the combined data group while simultaneously verifying the accuracy of the previously stored data group are determined. But the correction of the error check bits is not considered.

Triple track error correction

TL;DR: In this paper, a method for correcting errors in up to three tracks or channels in a multi-track data system is provided, where message data is formed into a codeword by adding three check bytes which are dependent on each other and are generated from the information bytes.
