Abstract
The technology of this disclosure relates to a signal modulating method, a signal demodulating method, a device, a storage medium, and a program product. In the signal modulating method according to a first aspect of this disclosure, a sending device modulates a bit sequence onto a plurality of subcarriers through binary phase shift keying (BPSK) constellation point mapping, dual carrier modulation (DCM), and a duplication (DUP) operation, where the plurality of subcarriers include a first group of subcarriers and a second group of subcarriers. Then, the sending device changes a phase of first data carried in the first group of subcarriers by 90 degrees or minus 90 degrees, and further generates a modulation signal based on the first data that is carried in the first group of subcarriers and whose phase has been changed and second data carried in the second group of subcarriers.
