    • PROBLEM TO BE SOLVED: To improve error correction.SOLUTION: An error correction data processing apparatus includes: a noise predictive calibration circuit operable to calibrate a first set of filter coefficients on the basis of a first data set and calibrate a second set of filter coefficients on the basis of a second data set; and a first noise predictive detector operable to receive the first set of filter coefficients. The apparatus further includes: a decoder operable to perform a first global iteration with the first noise predictive detector and determine a violation check count value; and a second noise predictive detector operable to receive the second set of filter coefficients if the violation check count value is less than a predetermined value, or to receive the first set of filter coefficients if the violation check count value is greater than the predetermined value.
    • 要解决的问题:改善纠错。解决方案:纠错数据处理装置包括:噪声预测校准电路,可操作以基于第一数据组校准第一组滤波器系数,并校准第二组滤波器系数 在第二数据集的基础上; 以及可操作以接收第一组滤波器系数的第一噪声预测检测器。 所述装置还包括:解码器,其可操作以与所述第一噪声预测检测器执行第一全局迭代并确定违反检查计数值; 以及第二噪声预测检测器,其可操作以在所述违反检查计数值小于预定值时接收所述第二组滤波器系数,或者如果所述违反检查计数值大于所述预定值,则接收所述第一组滤波器系数。
