With a total of 3 patents to his name, Afonin's work showcases his innovative spirit and technical expertise.

Latest Patents

One of Afonin's latest patents is titled "Impulse regular expression matching." This invention discloses a method and apparatus for matching regular expressions. It involves maintaining a buffer of symbols that provides the last occurrence positions of each symbol. When two constants match on either side of a regular expression operator, the buffer is queried to determine if a member of the complement of the operator occurred between the two constants. If such a member exists, the operator is not satisfied; otherwise, it is satisfied.

Another significant patent is "Majority-tabular post processing of quasi-cyclic low-density parity-check codes." This method focuses on finding a valid codeword based on a near codeword trapping in a low-density parity-check decoding process. It includes identifying trapping set configurations and applying corrections to produce trapping sets with a limited number of invalid checks. The configurations are corrected to produce a trapping set in a table, associating each corrected trapping set with a valid codeword.
