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 method includes: selecting, from M polar codes of a same code length and code rate, a polar code corresponding to an actual code rate for a first transmission, and encoding an information bit sequence by using the polar code to obtain encoded bits; and performing rate matching on the encoded bits to generate to-be-sent bits. Different from a traditional HARQ using one polar code, in this embodiment, a polar code corresponding to the actual code rate for the first transmission is selected from the M polar codes during the initial transmission, so that a different polar code can be selected adaptively according to the actual code rate for the first transmission.

Abstract: A redundant array of independent disks card, a command processing method, a storage apparatus and system are provided. The redundant array of independent disks card includes a control module and N front-end modules, where N is a positive integer greater than or equal to 2. An nth front-end module in the N front-end modules is configured to receive a command from an nth host module in N host modules, and send the received command to the control module. The control module is configured to receive commands from the N front-end modules and process the received commands. A storage apparatus provided with the redundant array of independent disks card can recover faulty data more quickly during data recovery. In addition, a more flexible erasure code scheme can be implemented by using the redundant array of independent disks card.
