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 3):
The RS error correction decoding method according to  claim 1 , wherein in the process of obtaining the remainder polynomial R(x) by dividing the code word polynomial Q(x) by the generator polynomial G(x), multiplication of the coefficients of x is performed, and the multiplication operation is converted into addition operation specifically as follows:\n representing the coefficients of x by a polynomial representation; multiplying and expanding the coefficients represented by the polynomial representation to obtain an addition of different power exponents of \u03b1; finding out the numerical values of the different power exponents of \u03b1 through the lookup table f(\u03b1 j ) to solve the addition.
