    Abstract: The operating circuit on GF (2m) using a Galois field GF (2m/2) includes converting means for converting an element expressed by a base on GF (2m) into an element expressed by a base on GF (2m/2), operating means for perfoming an operation of the element expressed as the base on the GF (2m/2) onto GF (2m/2), and inversely-converting means for inversely converting the element expressed as the base on the operated GF (2m/2) onto the element expressed by the base on GF (2m) to perform the corresponding method, thereby simplifying the circuit and reducing the speed.

    Abstract: The apparatus and method corrects errors in digital data by a method having no step to solve error location polynomial. The method comprises the steps of: (A) multiplying n-word data and parity check matrix (H) to obtain 4 elements (S0,S1,S2,S3); (B) finding that the n-word data has no error when S0=S1=S2=S3=0; (C) calculating D=S0S2+S1S1 and checking that D equals to 0; (D) calculating coefficients σ1 and σ2 according to equations 1=(S0S3 + S1S2)/D, σ2=(S1S3 + S1S1)/D when D is not zero; (E) calculating K=σ2/(σ1σ1); and (F) calculating error value error using K coefficient and correcting error.

    Abstract: The method calculates error values with a simple circuit of a little delay to correct error. The apparatus includes the 1st adder (110) for correcting the error in received data by adding the error value (Y1 or Y2) from a buffer memory (101) to the data received from a buffer memory section (100), an error discriminator (100) for detecting error, and a controlling section (190) for controlling overall operation of the apparatus.
