  • USE OF ERROR CORRECTION CODES TO PREVENT ERRORS IN NEIGHBORING STORAGE
    Publication number: 20210019226
    Abstract: Disclosed in some examples are methods, systems, storage devices, and machine readable mediums that utilize the ability of ECC to correct errors to actively prevent errors. The memory device determines whether a request to place data of a requested value at a requested location in the storage media is likely to interfere with other data stored at other locations on the storage media, and if so, changes the requested value to a second value that will not interfere (or has a lower probability of interfering) with neighboring data. The second value may be corrected to the requested value when a read request is made for that data using ECC.

  • SECURE AUTHENTICATION USING PUNCTURING
    Publication number: 20210021420
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for secure authentication using puncturing. An authentication system receives an encoded obfuscated authentication credential as part of an authentication request and accesses a stored authentication credential. The authentication system performs a puncturing of the encoded obfuscated authentication credential. The resulting punctured authentication credential includes a subset of individual values from the encoded obfuscated authentication credential. The authentication determines whether the punctured encoded data input corresponds to at least a portion of the stored authentication credential. In response to determining that the punctured encoded data input corresponds to at least a portion of the stored authentication credential, the authentication system approves the authentication request.

  • SMART SYMBOL CHANGES FOR OPTIMIZATION OF COMMUNICATIONS USING ERROR CORRECTION
    Publication number: 20210021287
    Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which optimize one or more metrics of a communication system by intentionally changing symbols in a bitstream after encoding by an error correction coder, but prior to transmission. The symbols may be changed to meet a communication metric optimization goal, such as decreasing a high PAPR, reducing an error rate, reducing an average power level (to save battery), or altering some other communication metric. The symbol that is intentionally changed is then detected by the receiver as an error and corrected by the receiver utilizing the error correction coding.

  • DATA TRANSMISSION USING PUNCTURING AND CODE SEQUENCES
    Publication number: 20210021373
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and binary sequences. A receiving device receives a sequenced data input that includes a set of individual values and performs a puncturing of the sequenced data input, yielding a punctured sequenced data input. The receiving device calculates correlation values for the punctured sequence data input and a set of predetermined data outputs. The receiving device determines whether any of the resulting correlation values exceeds a threshold correlation value. In response to determining that the correlation value calculated based on one of the predetermined data outputs exceeds the threshold correlation value, the receiving device determines that the sequenced data input corresponds to the predetermined data output.
