Abstract The spectrum detection (SD) is a critical step in cognitive radio (CR) to identify the available spectrum and avoid interference and harm to primary users (PUs). Nonetheless, the practical detection process is often compromised with problems of receptors uncertainty, shadows, and multipath fading. To overcome these problems, a cooperative SD scheme is proposed by exploiting the system multiantenna (MUA) with the multiuser diversity (MUD).

The SD gives unlicensed secondary users (SUs) the opportunity to use the licensed spectral band until the PU makes its appearance. By allowing the cooperation between the SUs of the same spectral band, the time of the detection is reduced and increases the general dexterity, which is the strong point of cooperative SD. In this paper, we proposed an SD scheme using a new MUA design. The scheme proposed is a clear difference compared to other systems because in this design weight of quantification is multiplied by each receiving antenna. The scheme has the ability to detect low-level signals to facilitate sharing between the SU and PU system.

The numerical results are made to prove the performance of the proposed system compared to the conventional system. The results obtained confirm the efficiency of the proposed scheme.

Frequency Modulation proves to be better in comparison to amplitude modulation and phase modulation, and the derivative of frequency modulation, narrow band FM (NBFM) is usually employed to overcome above mentioned problems in the communication system [13, 14]. Table-3 provides representation, bandwidth requirement. Application of sequential detection schemes for obtaining performance bounds of greedy users in the IEEE 802.11 MAC Abstract: The widespread deployment of wireless networks and hot spots that employ the IEEE 802.11 technology has forced network designers to put emphasis on the importance of ensuring efficient and fair use of network resources.

This MAC protocol is called CSMA cognitive MAC protocol, used for the purpose. Our results amply confirm that our proposed scheme achieves better performance compared to a.
