Abstract
Embodiments of the present invention provide a signal processing method and apparatus, a first device determines a target insertion position of a pilot sequence in a first frequency-domain signal based on the data bits in a first sub-data signal obtained by dividing data bits in a data signal, combines the pilot sequences with a second sub-data signal obtained by dividing the data signal according to the determined target insertion positions, to obtain the first frequency-domain signal; sends the pulse signal corresponding to the first frequency-domain signal to the second device. The second device determines the pilot sequences in the first frequency-domain signal corresponding to the pulse signal and determines the data bits corresponding to the insertion position of each of the pilot sequences in the first frequency-domain signal, to obtain the first sub-data signal; demodulates subcarriers in the first frequency-domain signal other than the pilot sequences, to obtain the second sub-data signal; splices the first sub-data signal and the second sub-data signal, to obtain the corresponding data signal. Based on the above processing, spectrum resource utilization rate can be improved.
