摘要： An error correcting apparatus is provided to omit unnecessary Chien search by determining the correction success of a data row in decoding a reed solomon signal or a BCH(Bose Chaudhuri Hocquenghem) signal. An error correcting apparatus includes a data saving unit(231). The data saving unit(231) saves a plurality of data rows individually having at least 2t + 1 number of symbols as a parity row. A syndrome calculating unit(501) calculates one set of syndromes from a first data row among the plurality of data rows. An error position polynomial expression calculating unit(504) calculates a coefficient of an error position polynomial expression from the set of syndromes. A determining unit(507) requests a second data row to the data saving unit(231) when determining correction failure and outputs a determined result of correction success when determining the correction success. A correcting unit corrects an error of the first data row using the coefficient of the error position polynomial expression and the set of syndromes when receiving the determined result of the correction success.

摘要： A reed-solomon decoder in a digital communication system is provided to reduce a size by removing registers and a multiplier connected to the registers required for a Chien search and a Forney algorithm treatment process. A reed-solomon decoder in a digital communication system includes a reed-solomon polynomial expression evaluation processor(110), a modified Euclidean processor(130), and an error corrector(150). The reed-solomon polynomial expression evaluation processor(110) calculates a syndrome for searching an error location by receiving a code word of received data, and generates an erasure location polynomial expression for searching a location of an erasure symbol based on erasure information inputted from the outside. The reed-solomon polynomial expression evaluation processor(110) outputs a modified syndrome by multiplying the syndrome by the erasure location polynomial expression, and calculates the error location and size of the received data by using the inputted error location polynomial expression and error evaluation polynomial based on the modified syndrome. The modified Euclidean processor(130) calculates the error location polynomial expression and the error evaluation polynomial expression based on the modified syndrome, and transmits the calculated value to the reed-solomon polynomial expression evaluation processor(110). The error corrector(150) corrects an error of the received data by receiving the error location and size of the received data from the reed-solomon polynomial expression evaluation processor(110).
