The purpose of this paper is to provide an overview and summary of the fundamental meaning and concepts of radio-frequency and wireless communication systems. It begins with a 2 summary of the history of wireless communications in general, from the first radio-frequency communication system to current cellular mobile radio systems. It then proceeds with the concept of radio wave propagation, forms of wireless communication systems and techniques, and the basic concept of cellular mobile radio communication. It classifies wireless communications into categories of related technology by grouping related concepts together. With subtopic Spectrum sensing is the key function in implementing cognitive radio, which enables secondary users to identify and utilize vacant spectrum resource allocated to primary users. Recent studies have proposed four major sensing methods, including matched filter, energy, feature, and eigen value-based detectors.. In a constant noise environment, the performance of the proposed detector approaches that of an ideal radiometer. Hence the proposed method has been implemented using sensing technique and different rules are been implemented.
