Abstract: Spectrum sensing enables cognitive radio systems to detect unused portions of the radio spectrum and then use them while avoiding interferences to the primary users. Energy detection and autocorrelation is one of the most used techniques for spectrum sensing because it does not require any prior information about the characteristics of the primary user signal. Here energy detection and spectrum sensing techniques both are used for spectrum sensing. This technique has helped to identify very low SNR signals.
