Fast method for wideband spectrum sensing

摘要: Embodiments of the present invention relate cognitive radar and RF technologies, more particularly, to spectrum sensing processing for rapidly monitoring channel availability activity. The goal is find use unoccupied channels broadcast receive information. According one embodiment, a method analyzing received signal determine unused channels, or frequencies, therein, comprises: anchor points that represent high energy frequency locations; calculating distances between determined points; identifying eliminating clusters isolated defined as region interference based on calculated distances; selecting at least remaining transmitting receiving signal. may further include performing an optional quality risk assessment frequencies waveform, from consideration in some instances.
