Abstract: This application provides a coding method, a decoding method, and a communications apparatus. The coding method includes: obtaining a first information bit sequence; determining a first frozen bit sequence based on a probability distribution value P1 of the first information bit sequence; determining a check bit sequence based on a second information bit sequence, where the second information bit sequence is the first information bit sequence or a sequence obtained after a pre-transformation operation is performed on the first information bit sequence; obtaining a first bit sequence based on the second information bit sequence, the check bit sequence, and the first frozen bit sequence, where the first bit sequence includes bits in the second information bit sequence.

Abstract: This application discloses encoding and decoding methods and a related apparatus, and is applied to the coding field. The method includes: obtaining a to-be-encoded first transport block; obtaining F sub-transport blocks based on the first transport block, where probability distributions of all preprocess blocks included in any sub-transport block belong to a same probability distribution range, and probability distributions of preprocess blocks included in at least two of the F sub-transport blocks belong to different probability distribution ranges; encoding the F sub-transport blocks to obtain a second transport block, where the second transport block includes F encoded sub-transport blocks, and at least two of the F encoded sub-transport blocks correspond to different code rates; and performing transmission based on the second transport block.

Abstract: This application provides a signal processing method and device. The method includes: A first device receives a first complex signal formed after an electromagnetic signal is reflected by an ambient environment. A dimension of the first complex signal is related to configuration information of the first device. The first device sends a transformed signal to a second device. The transformed signal includes a transformed bitstream, and the transformed bitstream is obtained by the first device by transforming the first complex signal based on the configuration information of the first device, so that the second device de-transforms the transformed signal based on the configuration information of the first device to obtain a second complex signal.

Abstract: Example encoding/decoding methods, communication apparatus, and systems are provided. One example encoding method includes encoding first data by using an encoding model, to obtain N pieces of encoded data, where N is an integer greater than 2. De-correlation is performed on the N pieces of encoded data to obtain N pieces of de-correlated encoded data, where a part or all of the N pieces of de-correlated encoded data may be for determining second data, the second data is for restoring third data, and the third data is the first data, or an approximation degree between the third data and the first data is greater than a specified threshold The N pieces of de-correlated encoded data are sent.
