Abstract
An object is to enable erasure correction even at the time of a degeneration operation and reduce the number of necessary parallel media through dynamic setting of degree of redundancy. A parallel data encoding/decoding system performs parallel data transmissions using a plurality of lanes from an encoder to a decoder. The encoder encodes products of elements of an encoding vector M of symbols of each lane and a state vector U indicating validity of the symbols, and transmits the state vector U along with a transmission vector Y obtained through the encoding. The decoder decodes a subset Mconstituted of valid elements of the encoding vector M using a received reception vector Y', the received state vector U, and an erasure vector E indicating whether each element of the transmission vector has been erased in a transmission/reception section.
