Abstract: PROBLEM TO BE SOLVED: To provide a signal processing method, a signal processing system, a program for the signal processing, and a computer-connectable recording medium for recording the processing program. SOLUTION: The signal processing method for the digital signal includes a step of formulating a Yule-Walker equations in a prescribed form of a matrix of elements in a Galois field (2 ) and a vector, including the element as a factor in the Galois field (2 ), a step of returning the solution of the equation to a calculation of a symmetric matrix in a Jacobi's formula, a step of determining the number of errors as the size of the maximum matrix corresponding to the solution other than zero, and a step of determining whether or not the number of errors is equal to the maximum number of correctable errors.
