Abstract: A signal transmission method includes: processing, by a base station, a first baseband signal, a second baseband signal, a third baseband signal, and a fourth baseband signal by using a VAM matrix, to obtain four processed signals; performing precoding processing on the four processed signals to obtain four coded signals; and sending the four coded signals to a mobile terminal by using four radio frequency ports. The four radio frequency ports are in a one-to-one correspondence with the four coded signals. A first processed signal is the same as a third processed signal, a second processed signal is the same as a fourth processed signal. The first processed signal is obtained by performing superposition on the first baseband signal and the third baseband signal, and the second processed signal is obtained by performing superposition on the second baseband signal and the fourth baseband signal.

Abstract: A communications apparatus includes a phase correction unit, a first radio frequency channel, a first analog bridge, a second radio frequency channel, and a second analog bridge. A first signal is sent to a first input end using the first radio frequency channel, and is divided into at least two channels of first sub-signals by using the first analog bridge. The at least two channels of first sub-signals are respective output from at least two first output ends to at least two first antenna arrays. Similarly, a second signal is divided into at least two channels of second sub-signals by using the second analog bridge, and the at least two channels of second sub-signals are output to at least two second antenna arrays. A first channel of first sub-signal and a first channel of second sub-signal are coupled to the phase correction unit by using a coupler.

Abstract: An image processing method includes an electronic device configured to perform style migration processing on a first image sequence based on a target migration style by using a fused style migration model into which a plurality of single-style migration models is fused in order to obtain a second image sequence. A style of a 1st frame of image to a style of a last frame of image in the second image sequence change in a first style order in styles of output images of the plurality of single-style migration models. The first image sequence may be from a video shot by using the electronic device. The electronic device may save a plurality of frames of images in the second image sequence as a video. The video may present an effect of rapid time lapse during play.
