This application discloses a signal processing method and an apparatus. The method includes: A transmit device generates a PPDU, where the PPDU includes a preamble, the preamble includes an LTF, the LTF includes a plurality of LTF symbols, and the plurality of LTF symbols may be used to carry a sequence obtained according to a first matrix; and then sends the PPDU. Correspondingly, a receive device receives the PPDU, and then processes, according to the first matrix, signals received on the plurality of LTF symbols. The first matrix is a Pn×n matrix, or the first matrix is obtained according to a Pn×n matrix, where P n × n × P n × n T = n × I , I is an identity matrix, the Pn×n matrix includes n rows and n columns, the P n × n T matrix is a transpose matrix of the Pn×n matrix, and n is an integer greater than 8.
