Abstract
This application discloses a data transmission processing method and apparatus, a communication device, and a storage medium. The data transmission processing method includes: performing, by a transmit end, spectrum spreading on to-be-transmitted data through K orthogonal sequences, to obtain K orthogonal data matrices; the transmit end maps the K orthogonal data matrices onto different frequency division multiplexing OFDM subcarriers, to obtain K first OFDM signals, where the first OFDM signals are spectrum spreading data matrix OFDM signals; performing, by the transmit end, inverse fast Fourier transform IFFT processing on a kfirst OFDM signal among the K first OFDM signals, to obtain a kfirst OFDM time domain signal; and the transmit end maps the kfirst OFDM time domain signal onto a ktransmit antenna, and transmits a first data signal through the ktransmit antenna.
