Abstract
Embodiments of this application provide a signal processing method and apparatus. A sending device sends a first symbol and modulates a phase of a second symbol based on a first phase, a second frequency, and a second duration. The second symbol is the next symbol after the first symbol. The first phase is a phase at the end of the first symbol. The second frequency is a transmission frequency used for the second symbol, and the second duration is a duration of a cyclic prefix of the second symbol. The sending device sends a modulated second symbol by using the second frequency, where phases between the modulated second symbol and the first symbol are continuous. This avoids a phase jump, and therefore reduces interference caused by a transmitted signal to a signal transmitted on an adjacent frequency band.
