Abstract: This application provides an encoding method and an encoding apparatus based on a polar code, to improve compression performance of a source sequence of a limited length. The method includes: obtaining a source bit sequence; encoding the source bit sequence by using a polar code generation matrix that is based on sub-block column transformation, to obtain a first bit sequence, where the polar code generation matrix that is based on the sub-block column transformation is determined based on a first polar code generation matrix and a transformation matrix, and the transformation matrix may achieve effect of performing sub-block column transformation on the first polar code generation matrix; and compressing the first bit sequence, to obtain a compressed bit sequence.

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 communication methods and apparatus are described. In one example method, a terminal device obtains and sends first information, where the first information indicates non-differential information of at least one first target point at a first moment. The terminal device obtains second information and sends the second information, where the second information indicates differential information of at least one second target point, and each of the at least one second target point corresponds to a first target point in the at least one first target point. Differential information of each of the at least one second target point is determined based on non-differential information of the second target point at a second moment and non-differential information of a corresponding first target point at the first moment, and each of the at least one second target point is a target point sensed by the terminal device at the second moment.

Abstract: This application discloses a communication method that comprises obtaining first data, where the length of the first data is A; compressing the first data into second data, where the length of the second data is C; and generating third data based on the second data, where the third data includes the second data and (T−C+p) alignment bits. T is a threshold in the J thresholds that is greater than or equal to C and the closest to C. The J thresholds correspond to A and are greater than 0, with J being a positive integer greater than or equal to 2. p is a quantity of auxiliary check bits and is an integer greater than or equal to 0. The communication method further comprises performing channel encoding on the third data to obtain fourth data and sending the fourth data.
