Executive Summary

Technique of multiple windows frequency estimation integrating SVD offers a efficient method which estimate interference temperature in radio frequency environment. Since this paper use a way which SVD integrate the neural network, the complexity of tradition arithmetic is predigested and the nicety of estimating interference temperature is improved. At the same time, the paper provides a good method for estimating the real time interference temperature in complex radio frequency environment. Today's wireless networks are characterized by a fixed spectrum assignment policy and according to frequency allocation bodies around the world; few frequency resources are currently available for future wireless applications. This spectrum limitation has had profound impacts on the research directions of wireless communications community.
