This application provides example symbol processing methods and apparatuses. One example method includes generating a first symbol in a symbol sequence, where the first symbol and a second symbol have a same first symbol component, a start location of the first symbol component in the first symbol is a start location of the first symbol, a start location of the first symbol component in the second symbol is a location at which a cyclic prefix is truncated in the second symbol, the second symbol is a next symbol adjacent to the first symbol, and the first symbol and the second symbol each has a cyclic prefix. The first symbol can then be sent.
