Description: Spectrum sensing requires the order of cognitive radio, looking for flexible use of opportunistic spectrum. In addition, it is the spectrum that disturbs the level of management caused by primary users (PUs). Remote sensing provides awareness of the radio operating environment. Cognitive stations can then adapt to its parameters such as carrier frequency power and waveform dynamics to provide the best service available to connect to meet user constraints on interference requirements. In wireless communication systems, we usually have some primary users who have knowledge of the waveform and the spectrum of the signal of the structure or statistic properties. This knowledge may be related to the modulation scheme, symbol or chip signal, channel speed.
