Correlation Analysis of Summation Generator
求和生成器的相关性分析

Dj. Golic applied linear sequential circuit approximation (LSCA) method to analyze the summation generator with an arbitrary number of inputs. He conjectured that he could obtain all pairs of mutually correlated input and output linear functions with the maximum possible absolute value of the correlation coefficient by this method, but he did not give any proof. By using Walsh Transformation technique, the conjecture is proved for even n in this paper. The "total correlation" of summation generator is studied which is very similar to that of combiners with one bit memory.
