42 results about "Group code" patented technology

In coding theory, group codes are a type of code. Group codes consist of n linear block codes which are subgroups of Gⁿ, where G is a finite Abelian group. A systematic group code C is a code over Gⁿ of order |G|ᵏ defined by n-k homomorphisms which determine the parity check bits. The remaining k bits are the information bits themselves.

Systems and methods for code clustering analysis and transformation

The present application is directed towards systems and methods for cluster-based code analysis and transformation. Cluster-based analysis may group code objects based on their similarity across functional areas, such as where a code object is cloned in multiple areas (e.g. sort functions that are duplicated across areas, or reports or tables that are identical). In some implementations, objects may be grouped into clusters by type, or based on reading from or writing to a common table. In some implementations, clustering at different layers may be possible.
