Cataloged from PDF version of thesis report. Includes bibliographical references (page 35-36). Demand of ever-present wireless services requires the use of more spectrum resources. However, present wireless networks are segmented by a fixed spectrum allocation policy. This fixed allocation of spectrum has lead to unused or underutilized bandwidth (namely spectrum holes) where opportunistic spectrum sharing increased its efficiency. To address this problem, cognitive radio is being uplifted as an emerging solution which uses intelligent technology to autonomously adapt in operating parameters in dynamic conditions. This paper starts with the illustrations of cognitive radio and classifications of spectrum sensing techniques which are then simulated by providing manual parameters through an algorithm in MATLAB. The simulation consist a set of dummy primary users who are set with specific bandwidth and using energy detection technique those spectrum bands are allocated dynamically to a set of secondary users during the idle period of the primary users. Lastly, a signal to noise ratio (SNR) manipulation has been implemented to observe how spectrum sensing is affected which in turn aided to understand spectrum allocation.
