Title:
METHOD FOR TRANSMITTING/RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM USING AUTO ENCODER, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/231026
Kind Code:
A1
Abstract:
The present specification provides a method for a transmitting end transmitting a signal in a wireless communication system using an auto encoder. More specifically, the method carried out by a transmitting end comprises the steps of: encoding input data on the basis of a pre-trained transmitting end encoder neural network; and transmitting a signal to a receiving end on the basis of the encoded input data, wherein the transmitting end encoder neural network serially comprises (i) a first encoder neural network for receiving the input data and outputting a first codeword, (ii) an interleaver for receiving the first codeword, interleaving same, and outputting the interleaved first codeword, and (iii) a second encoder neural network for receiving the interleaved first codeword and outputting a second codeword constituting the encoded input data.
