Title
Peak to Average Power Ratio sensor for green Cognitive Radio
Abstract
High Peak to Average Power Ratio (PAPR) is a critical issue in multi-standard and multi-carrier communication systems. This problem can result in large performance degradation due to the non-linearity of the High Power Amplifier (HPA) or in low power efficiency. The Cognitive Radio (CR) is an efficient technology to meet the Green communications concept. In this paper, we study the PAPR reduction in the context of amplifying signals of several standards. Also, we propose a scenario allowing an opportunistic spectrum access in the context of Cognitive Radio without degrading the system performance keeping the same Input Back-Off (IBO) and thus the same efficiency of the power amplifier. This scenario uses particular Cognitive Radio (CR) sensors, a Hole Detector sensor and a PAPR sensor. The principle of the proposed method will be described. Also, simulation results based on two Tone Reservation (TR) based PAPR reduction techniques will be given in order to validate the proposed concept.
