Abstract
Error correction in a data transmission system transmitting data as a sequence of data packets, each data packet containing a number of data bytes, employs parity bytes generated for each data byte in each data packet (e.g., row parity bytes) in conjunction with parity bytes for certain data bytes in predetermined data byte positions over a number of data packets (column data bytes). In a transmission arrangement, row parity bytes are generated and transmitted in a principal data channel along with the data packets, and column parity bytes are generated and transmitted in an ancillary data channel. In a receiver arrangement, row parity bytes are decoded in a principal data channel along with the data packets, and column parity bytes are decoded in an ancillary data channel and are employed to correct the data bytes in the principal data channel. A transmission system includes a transmission arrangement and a receiver arrangement communicating via a transmission medium.
