METHOD AND APPARATUS FOR ENCODING AND DECODING IN ELECTRONIC DEVICE

摘要

A method and an apparatus for encoding and decoding in an electronic device are provided. In a decoding method, at least one parity symbol is received. A Cauchy matrix is generated using the at least one parity symbol. A Cauchy submatrix is configured from the Cauchy matrix based on the number of at least one lost data symbol and an inverse matrix of the Cauchy submatrix is calculated. At least one parity symbol corresponding to the at least one lost data symbol is updated. The at least one lost data symbol is recovered using the updated at least one parity symbol.

1. A decoding method in an electronic device comprising:
receiving at least one parity symbol; generating a Cauchy matrix using the at least one parity symbol; configuring a Cauchy submatrix from the Cauchy matrix based on the number of at least one lost data symbol to calculate an inverse matrix of the Cauchy submatrix; updating at least one parity symbol corresponding to the at least one lost data symbol; and recovering the at least one lost data symbol using the updated at least one parity symbol.
