Abstract: Spectrum sensing for spectrum opportunities and interference detection has been thoroughly incorporated in this paper. A tri-sector based technique has been used to mitigate the interference during spectrum sensing in cognitive radio. In this paper we propose a cooperative framework in which we consider a tri-sectored cellular network served by a base station (primary transmitter) and two types of users (primary users and secondary users). Multiple antennas are placed both on primary users as well as secondary users to enhance the sensing probability of the target. The spectrum is sensed for different combinations of users and power spectral density (PSD) graph is plotted for each combination. We have also calculated capacity and signal-to-interference-noise-ratio (SINR) for tri-sectored cellular model, and the CDF plot depicts the enhancement of capacity and SINR for the proposed model. The results have been verified in terms of various graphs and plots and a few tables.
