    • PROBLEM TO BE SOLVED: To improve the error correction capability of an error correction technique.SOLUTION: In an error correction device, an error correction circuit of each stage includes a calculation circuit, a determination circuit and a correction circuit. The calculation circuit calculates a reliability of a codeword as a scale indicating the level of the possibility of errors in correcting the codeword. The determination circuit compares the reliability of the codeword calculated by the calculation circuit with a threshold, and determines whether or not the error correction circuit of the stage should correct the codeword in accordance with the result of comparison. The correction circuit corrects the codeword if the determination result indicates that the error correction circuit of the stage should make corrections. If the determination result indicates that the error correction circuit of the stage should not make any corrections, the succeeding error correction circuit redetermines whether or not to correct the codeword.
    • 要解决的问题:提高纠错技术的纠错能力。 解决方案:在纠错装置中,每一级的纠错电路包括计算电路,确定电路和校正电路。 计算电路将码字的可靠性计算为指示纠正码字的错误的可能性的级别的标度。 确定电路将由计算电路计算的码字的可靠性与阈值进行比较,并且根据比较结果确定舞台的纠错电路是否应该纠正码字。 如果确定结果表明舞台的纠错电路应进行校正,则校正电路校正码字。 如果确定结果指示级的纠错电路不应进行任何校正,则后续的纠错电路重新确定是否校正码字。 版权所有(C)2013,JPO&INPIT
