A multidimensional parity-check code (MDPC) is a simple type of error correcting code that operates by arranging the message into a multidimensional grid, and calculating a parity digit for each row and column. In general, an n-dimensional parity scheme can correct n/2 errors.The receiver can see that the first row and also the first column add up incorrectly. Using this knowledge and the assumption that only one error occurred, the receiver can correct the error. In order to handle two errors, a 4-dimensional scheme would be required, at the cost of more parity digits. In telecommunication and information theory, forward error correction (FEC) (also called channel coding) is a system of error control for data transmission, whereby the sender adds (carefully selected) redundant data to its messages, also known as an error-correcting code. This allows the receiver to detect and correct errors (within some bound) without the need to ask the sender for additional data.
