    Abstract: A communication method and apparatus is provided so that a fading channel can implement a good error correction capability. This helps improve information transmission reliability. The method includes: a transmit end device determines, based on N bit sets, a first sequence and a second sequence that are obtained through quadrature amplitude modulation QAM. The first sequence includes N in-phase components, and the second sequence includes N quadrature components; or the first sequence includes N quadrature components, and the second sequence includes N in-phase components, where N is an integer greater than or equal to 2. Then, the transmit end device performs interleaving processing on the first sequence, to obtain a third sequence. Then, the transmit end device sends, to a receive end device, a symbol sequence determined based on the second sequence and the third sequence. The symbol sequence includes N QAM symbols.

    Abstract: This application discloses a data processing method and an apparatus. The method includes: after obtaining first data, a first communication apparatus processes the first data based on a first parameter, to obtain a first transmission symbol, and sends the first transmission symbol to a second communication apparatus. Correspondingly, the second communication apparatus receives the first transmission symbol. The second communication apparatus processes the first transmission symbol based on the first parameter to obtain an input of a neural network, and processes the input by using the neural network to obtain a processing result. The first parameter is determined based on first accuracy and first channel information, the first channel information is information about a channel between the first communication apparatus and the second communication apparatus, and the first accuracy indicates accuracy of processing data by the neural network.

    Abstract: A photographing method and an electronic device are provided, so that a to-be-photographed target can continue to be tracked after the to-be-photographed target returns to a shooting image, to improve accuracy of focusing performed during photographing of a moving object. The method includes: displaying a first image including a first object and a tracking indicator that is associated with the first object, the tracking indicator indicating that the first object is a tracked target; displaying a second image that does not include the first object or the tracking indicator; displaying a third image including the first object; automatically setting the first object as the tracked target and displaying the tracking indicator associated with the first object; and automatically focusing on the first object when displaying the third image.

    CPC classification number: H04B7/18532

    Abstract: This application discloses a NB-IoT-based communication method and an apparatus, to evolve a NB-IoT communication technology into an NTN. The method is as follows: A terminal device generates an uplink signal, including a superframe which includes a synchronization sequence located in first duration of the superframe and a data frame located in second duration which is after the first duration, the synchronization sequence successively includes a first sequence repeated Ni times and a second sequence repeated N2 times, the second sequence is obtained by multiplying the first sequence by −1, a part of consecutive sequences of the synchronization sequence are used as a first synchronization reference sequence that is obtained based on the second sequence repeated N2 times and one or more first sequences that are sorted from back to front in the first sequence repeated N1 times. The terminal device sends the uplink signal to a network device.
