  • Publication number: 20250039021
    Abstract: In a method for sending signals in network communications, an apparatus obtains a plurality of extended sequences, with each extended sequence comprising an original sequence and an additional sequence. In each extended sequence, the additional sequence is located before the original sequence, and the additional sequence includes last m codes of the original sequence. Alternatively, the additional sequence is located after the original sequence, and the additional sequence includes first n codes of the original sequence. The apparatus generates a plurality of target sequences based on the plurality of extended sequences and a security code corresponding to each extended sequence. The apparatus then generates a first impulse signal based on the plurality of target sequences, and sending the first impulse signal.

  • Publication number: 20250015832
    Abstract: The present disclosure relates to signal transmission methods and apparatuses. One example method includes spreading a preamble symbol based on a first spreading code sequence to generate a first signal, and sending the first signal to a receiver. The first signal is used to determine a channel impulse response. The first spreading code sequence includes a plurality of spreading code groups, each spreading code group includes a plurality of same spreading codes and at least one guard symbol, at least one of a first bit or a last bit of each spreading code group is a guard symbol, and the plurality of spreading code groups include at least two spreading code groups with different spreading codes.
