Claim:
1. A decoding method in an electronic device comprising: receiving at least one parity symbol; generating a matrix comprising a plurality of elements in a form of a Cauchy matrix based on the at least one parity symbol; configuring a Cauchy submatrix from the matrix based on a number of at least one lost data symbol to calculate an inverse matrix of the Cauchy submatrix; updating the at least one parity symbol corresponding to the number of at least one lost data symbol by multiplying the inverse matrix of the Cauchy submatrix to the at least one parity symbol; and recovering the number of at least one lost data symbol using the updated at least one parity symbol, wherein each of the plurality of elements is determined based on at least one of first sets including Galois Field elements and at least one of second sets including Galois Field elements, and wherein each of the Galois Field elements included in the at least one of first sets is different from each other and each of the Galois Field elements included in the at least one of second sets is different from each other.
