Abstract
A signal sending method, a signal receiving method, and a device for signal transmission or receiving are provided. A part that is of a first signal and that is carried on a ksubcarrier in an isubcarrier group in N subcarrier groups is x(k), and a sequence {s(k)} related to x(k) is one of enumerated sequences. The enumerated sequences are sequences with relatively good cross-correlation. Therefore, for two subcarrier groups, provided that selected {s(k)} is two of the enumerated sequences, cross-correlation between signals carried in the two subcarrier groups can be ensured to be relatively good, thereby reducing interference between the signals and improving channel estimation performance.
