  • Publication number: 20260254703
    Abstract: A terminal includes: a control unit configured to: map bit sequences to indices; output one-hot encoder vectors associated with the indices; and pre-train a neural network (NN) to output modulated symbols in response to the one-hot encoder vectors and a variance of phase noise as inputs; and a transmitting unit configured to carry out a transmission to a base station by using modulated symbols that are selected based on a constellation generated by the pre-trained NN.

  • Patent number: 12634187
    Abstract: The present disclosure provides a transmitting device, a receiving device and a modulation method. The transmitting device includes: a receiving unit configured to obtain a bit sequence to be transmitted; a control unit configured to perform pseudo-N-order first type of modulation on the bit sequence to be transmitted, according to information about phase noise, wherein 2{circumflex over (?)}N first symbols of the pseudo-N-order first type of modulation correspond to a part of 2{circumflex over (?)}M second symbols of M-order second type of modulation, where M and N are positive integers.
