Abstract
A method of a transmitting device in a wireless communication system, includes: obtaining an encoded bit stream from information bits using a polar code; transmitting a first signal generated through a first modulation of the encoded bit stream; performing reverse mapping on the encoded bit stream; and transmitting a second signal generated through a second modulation of the reverse-mapped encoded bit stream.

A method performed by a transmitting device in a wireless communication system, the method comprising:
- generating, using a polar code, an encoded bit stream from information bits;
- transmitting a first signal generated by a first modulation of a first demultiplexed bit stream, wherein the first demultiplexed bit stream is generated based on the encoded bit stream using a demultiplexer (DEMUX);
- transmitting a second signal generated by a second modulation of a second demultiplexed bit stream, wherein the second demultiplexed bit stream is generated based on the encoded bit stream using the DEMUX and a cyclic shift of a designated size,
- wherein a mapping order of the second demultiplexed bit stream is reverse of a mapping order of the first demultiplexed bit stream.
A method performed by a receiving device in a wireless communication system, the method comprising:
- receiving a first signal generated by a first modulation of a first demultiplexed bit stream, wherein the first demultiplexed bit stream is generated using a demultiplexer (DEMUX);

- and
- obtaining information bits of a bit stream by combining the first signal and the second signal,
- wherein the bit stream is encoded using a polar code, and
