摘要： The embodiments of the present application provide a polar code construction method and apparatus, which relate to the field of communications technology. The method comprises: obtaining a polar weight spectrum for each polarized channel; calculating an upper bound of error probability of each polarized channel based on the obtained polar weight spectrum, distribution probability density of a fading factor of a fading channel, and a signal-to-noise ratio of the fading channel; taking a logarithm of the calculated upper bound of the error probability for each polarized channel and obtaining a reliability metric of the polarized channel based on the taken logarithm, wherein the smaller the metric value is, the higher the reliability of the polarized channel is; sorting all polarized channels in an ascending order of the reliability metric and selecting part of the polarized channels having a lowest reliability metric for transmitting information bits and the remaining polarized channels for transmitting frozen bits. According to the embodiments of the present application, performing polar code construction under the condition of a fading channel can improve the efficiency of polar code construction.

摘要： A system and method for providing erasure code protection across multiple storage devices. A data switch in a storage system connects a plurality of storage devices to a remote host. Each storage device is also connected to a controller, e.g., a baseboard management controller. During normal operation, read and write commands from the remote host are sent to respective storage devices through the data switch. When a write command is executed, the storage device executing the command sends a copy of the data to the controller, which generates and stores erasure codes, e.g., on a storage device that is dedicated to the storage of erasure codes, and invisible to the remote host. When a device fails or is removed, the controller reconfigures the data switch to redirect all traffic addressed to the failed or absent storage device to the controller, and the controller responds to host commands in its stead.

摘要： A method of operating a memory system includes receiving information data corresponding to a second program unit that is a part of a first program unit and a write request for the information data from a host; generating a codeword by performing error correction code (ECC) encoding on the received information data such that a partial parity bit corresponding to the information data among all parity bits of the codeword is updated; and providing a memory device with the generated codeword and a write command regarding the codeword.

摘要： An improved technique involves assigning a different generator matrix to each data stripe of the redundant disk array such that all of the different generator matrices represent the same code. For example, when a k×n generator matrix G represents a linear code C, k being the block length and n the code length, then for any invertible k×k matrix P, the matrix G′=PG is also a generator that represents C. When C is a systematic code, then G consists of a k×k identity matrix representing payload data concatenated with a k×(n−k) parity matrix representing parity data. Certain matrices P represent row operations on G, meaning that the matrix G′ may have the columns of the identity matrix in G to different locations in G′.

摘要： A method for storing and propagating error information in computer programs, in which a globally valid error variable is used for storing and propagating the error information, wherein for each recognized error a nonzero value for the error is added to the error variable as error information with a respective stipulated arithmetic sign, and wherein the value is formed from a discrepancy in the content of a coded variable from an expected value. This combination and integration of a separate global propagation variable with values derived from an error, particularly by virtue of detected discrepancies in the known error recognition and propagation paths using operations and operands in “coded processing”, achieves an increased propagation certainty.
