SIGNAL TRANSMISSION DEVICE, PARAMETER DETERMINATION DEVICE, SIGNAL TRANSMISSION METHOD, PARAMETER DETERMINATION METHOD, AND RECORDING MEDIUM

摘要

This signal transmission device (1) comprises: a distortion compensation means (11) for performing a distortion compensation process on an input signal (x) using a neural network (112) provided with L+1 computation layers including L intermediate layers (112M) (where L is a variable indicating an integer equal to or greater than 1) and an output layer (112O); a storage means (13) for storing a plurality of parameter sets (131), each of which includes the parameters of Q computation layers (where Q is a variable indicating an integer equal to or less than L) among the L+1 computation layers; and an application means (142) for selecting a parameter set from among the plurality of parameter sets on the basis of the signal pattern of the input signal and applying the parameters included in the selected parameter set to M computation layers. The parameters of the other computation layers other than the Q computation layers among the L+1 computation layers are fixed.
