Method for restoring lost and corrupted data transmitted from transmission apparatus to receiver, involves performing calculation-, transmission and stopping processes until number of iterations is reached such that window position is moved

摘要

The method involves calculating a variable node probability value for variable nodes in a defined window. The probability value is transmitted to check nodes in the window. A check node probability value for each check node is calculated and transmitted to the variable nodes. Bit values assigned to the variable nodes are estimated. Iteration in the window and displacement of the window are stopped when the bit values meet parity checks equations in a current window position. All the processes are repeated until a maximum number of iterations is reached such that a window position is moved.
