A method and electronic device for encoding data are provided. The method includes acquiring sets x(j=1 . . . k) and y(i=1 . . . p) in generating a Generator Cauchy Matrix, wherein k denotes a number of information symbols, and p denotes a number of parity symbols, generating a matrix A1 using the sets xand y, wherein elements of the matrix A1 are obtained by and have weight of Galois field, and the matrix A1 has a size of P&#xd7;K, generating a set K, wherein all elements of the set K are not included in the sets xand y, updating the set xby changing at least one element of the set xfor an element of the set K, updating the set yby changing at least one element of the set yfor the set K element, generating the Generator Cauchy Matrix using the updated sets xand y, and encoding data including the information symbols and parity symbols using the Generator Cauchy Matrix.

Data encoding method and electronic device therefor

A method and a system for estimating a parameter in a communication system are provided. The method includes estimating a parameter of a data channel model in a communication system, decoding a packet received through a determined noise channel to convert the packet into data indicating one of a success and failure of a reception of the packet, configuring a prototype channel having at least one unknown parameter, estimating the at least one unknown parameter using the data indicating the one of the success and the failure of the reception of the packet, and determining the size of a parity field of a forward error correction (FEC) symbol, using the estimated at least one unknown parameter.
