Research Abstract

In this research project, the maximum likelihood method of code acquisition was proposed, and the acquisition-based and bit error-based capacities are compared. A low-complicity method of code acquisition was proposed. With respect to generalized linear models, the entropy correlation coefficient and coefficient of determination were proposed, and statistical properties were investigated.
