1. A signal modulating method, comprising:
modulating 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, wherein
the plurality of subcarriers include a first group of subcarriers and a second group of subcarriers;
changing a phase of first data carried in the first group of subcarriers by a first angle, wherein
the first angle is plus or minus 90 degrees; and
generating a modulation signal based on the first data carried in the first group of subcarriers and second data carried in the second group of subcarriers.
