Abstract: An input method and a smart terminal device. After a processor in the smart terminal device determines, based on a first detection solution of a first infrared sensor, that a target object enters or leaves a first space range from a first plane, the processor starts or stops displaying a cursor based on distances measured by ultrasonic sensors; and after the processor determines, based on a second detection result of a second infrared sensor, that the target object enters or leaves a second space range from a second plane, the processor starts or stops performing a confirmation operation based on a location of the cursor.

Abstract: A polar code rate matching method and apparatus are provided. The method includes: performing bit reversal order interleaving on a polar code output by a polar code encoder, to obtain interleaved bits; and determining, based the interleaved bits, a rate-matched output sequence. By performing bit reversal order interleaving on a polar code, a rate-matched output sequence is obtained, which can reduce an FER, thereby improving HARQ performance and ensuring reliability of data transmission.

Abstract: The present invention provides a coding method and a coding device. The coding method includes: coding information bits a to be coded via cyclic redundancy check CRC, then inputting the bits coded via the CRC into an interleaver determined by a construction parameter of a Polar code, where the interleaver is configured to interleave the bits coded via the CRC and output interleaved bits; and coding the output interleaved bits via the Polar code to obtain a coded Polar code. The above method is used to solve a problem in the prior art that minimum code distance of a Polar code is not large enough when the Polar code is relatively short or is of a medium length.

Abstract: A method for performing polar coding is disclosed in the application. A data block is segmented into a plurality of first blocks. Difference in bit length between any two first blocks is not more than one bit. For each first block, one or more consecutive padding bits is added to obtain a second block of a bit length K if the bit length of the first block is less than K, so as to obtain a plurality of second blocks corresponding to the first blocks. N-K consecutive bits are added to each of the second blocks to obtain a plurality of third blocks. Polar encoding is performed on the third blocks.

Abstract: A Polar code rate matching method and a rate matching apparatus are disclosed. The method includes: dividing a system Polar code output by a Polar code encoder into system bits and parity bits; interleaving the system bits to obtain a first group of interleaved bits, and interleaving the parity bits to obtain a second group of interleaved bits; and determining a rate-matched output sequence based on the first group of interleaved bits and the second group of interleaved bits. System bits and parity bits are separately interleaved, to obtain a rate-matched output sequence, so that a sequence structure after interleaving is more random, which can reduce an FER, thereby improving HARQ performance, and ensuring reliability of data transmission.
