Abstract
A hardware architecture for systematic erasure encoding includes first matrix constructor circuit that receives parity-check matrix H for codeword C, and the erased part of codeword C, and outputs matrix Hof columns of H located on erased coordinates of code C; second matrix constructor circuit that receives matrix H and the erased part of codeword C and outputs matrix Hof columns of H located on non-erased coordinates of code C; a neural network that calculates matrix Jthat is an approximate inverse of matrix H. The matrix Jis used to determine new erasures in the parity matrix H and new erased coordinates. Matrices Hand Hare updated, and the updated His provided as feedback to the first matrix constructor circuit. A calculator circuit restores the erased coordinates of codeword C, from the matrix J, matrix H, and a non-erased part of codeword C.
