Title:
SIGNAL SENDING METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/201944
Kind Code:
A1
Abstract:
Disclosed in the present application are a signal sending method and a communication apparatus. The signal sending method comprises: acquiring a plurality of extended sequences, wherein each extended sequence comprises an original sequence and an additional sequence, which original sequence comprises N codes, N being a positive integer, and the original sequence and the additional sequence in each extended sequence meet the following conditions of the additional sequence being located before the original sequence and the additional sequence comprising the last m codes in the original sequence, or the additional sequence being located after the original sequence and the additional sequence comprising the first n codes in the original sequence, m and n being positive integers less than or equal to N; generating a plurality of target sequences according to the plurality of extended sequences and a security code corresponding to each extended sequence, wherein the plurality of target sequences comprise target sequences which correspond to the extended sequences and are generated according to the extended sequences and the corresponding security codes; and generating a first pulse signal according to the plurality of target sequences, and sending the first pulse signal. The method of the present application can reduce interference between sequences during the sending of signals, and can improve sequence orthogonality and the accuracy of subsequent processing processes.
