Abstract
It is an object of this invention to carry out error correcting coding for random errors and cell loss effectively and to obtain a transmitter for coding error correction codes and a receiver for decoding error correction codes on a transmission frame which minimizes transmission delay. This apparatus includes several elements. A buffer memory divides N data symbols of a data transmission cell into p blocks and stores the p data blocks for each of L cells to form a transmission frame. A check code generator carries out the error correcting coding in the unit of p blocks in a direction orthogonal to the direction of transmission. A cell composer selects a specific cell of p blocks having N data symbols and generates a transmission cell. A counter appends an identifier to the top of cells in the transmission direction. The cell with the identifier is transmitted after being replaced with a part of the coding cells as requested.
