Cognitive radio energy based spectrum sensing using MIMO

Today, energy spectrum is in high demand as the usage of the spectrum increase day by day at a tremendous rate; there is a need to find a way to efficiently utilize these scarce resources, cognitive radio is a huge step towards this. An enormous research papers have been published in various international conferences as well as journals in the last few years to make cognitive radio applicable with various applications as well as to make it better suit with various environmental scenarios. On the other side MIMO opened the door for many researches in the form of high diversity and reliability achieved within it compared to SISO. Very much research has been noticed in each individual direction but very few approach found in literature where both are combined & utilized. In this research paper cognitive radio scheme is implemented with MIMO, energy spectrum sensing is used for spectrum sensing as it is a simple and easy to implement. The simulation results indicate MIMO-cognitive radio outcomes SISO-cognitive radio. Simulation results have been expressed with various modulation techniques and detection probability and false probability are used as performance metrics.
