SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/041522
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a signal processing method and apparatus. The method comprises: a sending device sending a first symbol, and modulating the phase of a second symbol according to a first phase, a second frequency and a second duration, wherein the second symbol is the symbol coming 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 by the second symbol, and the second duration is the duration of a cyclic prefix of the second symbol; and using the second frequency to send the modulated second symbol, wherein the phase of the modulated second symbol and the phase of the first symbol are continuous. That is, before sending the second symbol, the sending device can modulate the phase of the second symbol, so as to change the phase of the second symbol, such that the phase of the first symbol and the phase of the second symbol are continuous, thereby avoiding a phase jump, and thus reducing the interference of a signal, in the transmission process, on a signal which is transmitted on an adjacent frequency band.
