Background: Due to the huge development of wireless devices and mobile data traffic
had gained attention towards identifying accurate solutions for more proficient utilization of the
wireless spectrum. An essential issue confronting the future in wireless systems is to identify the
appropriate spectrum bands to satisfy the request of future administrations. While the greater part
of the radio spectrum is allocated to various services, applications and users show that spectrum
usage is quite low.
Materials and Methods: The spectrum sensing is performed at the start of each time slot before
the data transmission. As a promising framework to improve the spectrum utilization, Cognitive
Radio (CR) technique has the immense potential to meet such a necessity by permitting unlicensed
users to exist together in licensed bands. In this paper Cognitive radio and Full-Duplex
(FD) based two-way relay communications are developed to enhance spectrum utilization for multichannel
and to decrease the false alarm rate.
Results: To solve the optimization problems in spectral efficiency, soft computing techniques is
proposed to minimize the self-interference and delay to the licensed users. In this proposed work
the kurtosis parameter is used for channel detection to determine whether the signal is present or
Conclusion: The performance results of the proposed method are evaluated in terms of spectral
allocation and outage probability which achieves better performance than the existing Multi-
Objective Genetic Algorithm (MOGA) optimization.
