With a total of 12 patents to his name, Bickerstaff's inventions reflect his commitment to enhancing technology through innovative solutions that address pressing technical challenges.

Latest Patents

Among his latest patents, Bickerstaff has developed a "Modified branch metric calculator to reduce interleaver memory and improve performance in a fixed-point turbo decoder." This invention introduces a turbo decoder that calculates alpha, beta, and gamma (branch metric) values without normalizing the branch metric. Instead, it applies a normalization factor to the newly calculated extrinsic values before storing them in interleaving memory. This approach not only reduces memory usage compared to previous turbo decoders but also improves the sensitivity of the decoder by omitting the normalization in the gamma calculation.

Another notable patent by Bickerstaff is in the realm of information security, titled "Information security and delivery method and apparatus." This innovative method involves secure data storage within a mobile communication device. The device securely stores user data and transmits it only upon the correct entry of authentication information, ensuring that the user cannot access the transmitted data. This inventive approach enhances data security in mobile communications.
