With the rapid development of modern communication technology, communication networks become increasingly complex environment. In order to monitor if the wireless signal with the same frequency is illegal, this paper proposes a method of intelligent recognition to CDMA2000 based on spectral correlation. First, the power spectrum is used for initial comparison, then, we use spectral correlation to...
With the rapid development of modern communication technology, the communication network environment becomes more and more complex. Aiming to meet the requirement of identifying the wireless signal, which is located in the same frequency band of WCDMA defining as an intelligent monitoring method based on spectral correlation has been identified effectively. Firstly, the power spectrum of the frequency...
