Abstract: The present disclosure provides a transmitting device, a receiving device and a receiving method. The receiving device includes: a receiving unit configured to receive information about a modulation parameter indicating a spiral factor; a control unit configured to determine pseudo-N-order first type of modulation according to the modulation parameter, 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, and M and N are positive integers.

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.
