Abstract
Cognitive radio technology is a kind of intelligent spectrum sharing technology, it can perceive spectrum environment selfly through certain method, look for unused spectrum (spectrum cavity), adjust the communications terminal parameter settings and realize the involvement of free spectrum resources, so as to improve spectrum efficiency, alleviate the purpose of spectrum resources nervous. Combing cognitive radio technology with ultra broadband wireless communications technologies, devise a new intelligent wireless system - cognitive ultra broadband wireless communication system (CUWB). In CUWB system, the selection of spectrum perception technology is vital, and restricts the whole system performance. Based on the noparametric estimation method, guarantee the accuracy of cases, realize the rapid estimate of interference temperature.
