Information processing device, information processing method, and program

An information processing device comprising:

• an acquisition unit that acquires each of one or more pieces of second data, in which information indicating positions of signal elements in a second signal is associated with at least some signal elements of the signal elements in the second signal, the second signal having a shorter signal length than a signal length of a first signal and being obtained such that the first signal including one or more non-zero components based on first data and one or more zero components is encoded on a basis of a matrix generated in accordance with a predetermined condition, from one or more devices connected via a network;
• and
• a signal processing unit that decodes the first data on a basis of the one or more acquired pieces of second data and a restriction condition in accordance with row components corresponding to the signal elements associated with at least the second data among the row components of the matrix.

An information processing method comprising:

• encoding, by a computer, a first signal including one or more non-zero components based on first data and one or more zero components to a second signal having a shorter signal length than a signal length of the first signal on a basis of a matrix generated in accordance with a predetermined condition;
• and
• transmitting, by the computer, each of one or more pieces of second data, in which information indicating positions of signal elements in the second signal is associated with the signal elements in the second signal, to one or more devices connected via a network.
