Kind Code:
A1
Abstract:
A communication system SYS, provided with a transmission device 1 and a reception device 2. The transmission device comprises: a conversion means 111 for converting a bit series Z having bit length b into a bit series Y that includes w-1 (w: an integer equal to or greater than 2) bits 1 and that has a bit length n (n > b); a conversion means 112 for converting the bit series Y into a bit series X having bit length t (t < n); and a neural network 113 that has t input nodes and that outputs, when the bit series X is inputted thereinto, a value relating to a feature amount of a transmission signal Tx. The reception device comprises: a neural network 212 that has t output nodes and that , when a feature amount of a reception signal Rx is inputted thereinto, outputs a numeric data series U including t items of numeric data; a conversion means 213 for converting the numeric data series U into a numeric data series Y' including n items of numeric data; and a generation means 214 for performing, on the numeric data series U, a reverse conversion of the conversion process performed by the conversion means 111, and thereby generating a bit series Z' having bit length b.
