Cognitive radio is a promising technique for efficient utilization of idle authorized spectrum since it is able to sense the spectrum and reuse the frequency when the primary user is absent. Spectrum sensing is the inherent ability of cognitive radio to autonomously perform required calculations and detect unused spectrum which can be used for a multitude of purposes. This paper investigates what cognitive radio systems that require focusing on the spectrum sensing device. Taking two voice applications which running under different Orthogonal Frequency Division Multiplexing (OFDM) schemes. These devices are Wi-Fi and wireless microphone.
