Abstract

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.
