Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The method of claim 1, wherein a value of the partial sign change applied to the lower half frequency domain of the higher RU is −1,
wherein the first data is generated by performing constellation mapping on encoded data bits based on binary phase shift keying (BPSK) and dual carrier modulation (DCM) in the lower RU,
wherein the encoded data bits are distributed only to the lower RU,
wherein a first pilot tone for the first data is inserted into the lower RU after the first data is generated,
wherein a second pilot tone for the second data is inserted into the higher RU after the second data is generated,
wherein the partial sign change is not applied to the first and second pilot tones.
