Abstract:
A decoding method includes that when encoding at a sending terminal, for a m-order primitive polynomial P(x), a primitive field element in galois field GF(2 m ) is represented by α; a lookup table f(α j ) for different power exponents of α is established, where the value of j is selected from all the integers ranging from 0 to 2m−1, with a total number of 2m; a generator polynomial G(x) is expanded to obtain a polynomial with respect to x, with coefficients being an addition or subtraction of the power exponents of α; a remainder polynomial R(x), obtained by dividing code word polynomial Q(x) by the generator polynomial G(x), is a polynomial with respect to x, with coefficients being an addition or subtraction of the power exponents of α; and the coefficients of the generator polynomial G(x) and the remainder polynomial R(x) are both calculated using data found in the lookup table f(α j ).

Claim (Index 6):
The RS error correction decoding method according to  claim 4 , wherein calculating the correction value using the correctors S 1  to S 2s  is specifically as follows:\n obtaining a equation set consisting of the location of the error information code and the correction value, wherein the error information code is the root of the equation set, and the correction value is an unknown number of the equation set; representing the correction value of the equation set by the polynomial representation, with standard bases being different power exponents of \u03b1, and coefficients being values of x i , i=0, 1, . . . , m; representing the location of the error information code of the equation set by the polynomial representation, with standard bases being different power exponents of \u03b1; bringing the correction value and coefficients represented by the polynomial representations into the polynomial of the equation set; letting the coefficient of each term of the polynomial be zero, thus obtaining a non-homogeneous linear equation set for x i ; solving the non-homogeneous linear equation set to obtain the value of x i ; bringing the value of x i  into the correction value represented by the polynomial representation to obtain by calculation the root of the equation set so as to obtain the correction value.
