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 Msub constituted 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.

Abstract: In the optical transport system a transport frame generator divides a transport frame accommodating plural client signals into plural transmission signals. Subcarrier transmission units convert the signals into optical signals using different optical carriers and transmit the converted optical signals. Subcarrier reception units receive the transmitted optical signals and convert the optical signals into reception signals. A transport frame termination unit combines the reception signals to restore the transport frame. A time-demultiplexing processor time-demultiplexes the restored transport frame to be separated into the client signals. A time slot control unit determines a new time slot allocation when time-multiplexing the client signals in the transport frame and stops supply of electric power to a subcarrier transmission unit and a subcarrier reception unit that transmit and receive an optical signal to which the client signals are not allocated.
