Abstract

Due to the development of radio service and the limitation of the frequency spectrum, spectrum multiplexing has been attached more and more attention. Spectrum Detection Technology is particularly important. This article has designed a weak signal detection system based on the Duffing oscillator which uses a two-level array detection algorithm to do fast detection. Then the article proposes a new state determination algorithm-TICTACTOEMIDLET algorithm. It uses the distribution character of the sample value of the phase trace to determine the state of the system. The simulation result shows the algorithm can detect the spectrum accurately.
