His innovative work has the potential to enhance data transmission and error correction processes.

Latest Patents

Chang Shu holds a patent for a "Fast efficient decoder for low distance RS and BCH codes." This illustrative decoder comprises a syndrome calculator, a location finder, and an error corrector. The syndrome calculator utilizes an array of logic gates to derive syndrome values from a received message vector and a parity check matrix. These syndrome values include at least three ten-bit syndrome values, denoted as S, S, and S. The location finder determines the number of errors based on the syndrome values and employs a second array of logic gates to compute two polynomial roots. This process involves deriving a product of a syndrome value vector and a quadratic solution matrix when the number of errors is two. The quadratic solution matrix is essential for determining the trailing coefficient value of a quadratic equation, its roots, and for reversing variable substitutions. Additionally, the location finder identifies a bit index for each of the polynomial roots.
