The research based on the related network broadband spectrum sensing algorithm of pn code ranging. More than the traditional spectrum sensing method based on narrow band as the research basis, through the radio-frequency head band pass filter center frequency change and implementation, therefore, not effective spectrum of broadband usage in real time tracking and perception, therefore, put forward the network broadband spectrum sensing algorithm based on pseudo code ranging. Spectrum resource usage through the main user judgment, build relevant spectrum perception model, according to theory of time serial search for pseudo code capture, until the results reached the preset threshold, enter the pn code tracking, according to the obtained phase difference sequence regulating local phase to achieve two sequences are minimum steady-state phase, implementation pseudo-code tracking, thus complete the perception of broadband spectrum and tracking. The experimental results show that the improved algorithm for network broadband spectrum perception can effectively reduce because of the negative impact of such factors as the channel fading and improve the processing speed and the reliability of perception, to provide data support to improve the utilization rate of spectrum resources, has a great advantage.
