description This application discloses a signal sending method and a communication apparatus. The method includes: obtaining a plurality of extended sequences, where each extended sequence includes an original sequence and an additional sequence, the original sequence includes N codes, and N is a positive integer; and the original sequence and the additional sequence in each extended sequence meet the following: the additional sequence is located before the original sequence, and the additional sequence includes last m codes of the original sequence; or the additional sequence is located after the original sequence, and the additional sequence includes first n codes of the original sequence, where m and n are positive integers less than or equal to N; generating a plurality of target sequences based on the plurality of extended sequences and a security code corresponding to each extended sequence, where the plurality of target sequences include a target sequence that corresponds to each extended sequence and that is generated based on each extended sequence and a corresponding security code; and generating a first impulse signal based on the plurality of target sequences, and sending the first impulse signal. According to the method of this application, interference between the sequences in the sent signal is reduced, and orthogonality of the sequences and accuracy of a subsequent processing process are improved.
