Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  considers a spectrum sharing wireless environment, where an OFDM-based cognitive radio system is allod to access the spectrum originally licensed to an OFDMA primary system. A new criterion referred to as the rate loss constraint, in the form of an upper bound on the maximum rate loss of the primary user due to the secondary transmission, is proposed for primary transmission protection. In addition, assuming that some PUs are protected by the rate loss constraint, and some PUs are protected by the interference por constraint, the optimal por allocation strategy to maximize the rate of the cognitive radio system under such a hybrid protection to PUs together with a transmit por constraint is derived. Then, the relationship beten the rate loss constraint and the interference por constraint is investigated, and it is shown by simulation that the cognitive radio system can achieve a significant rate gain under the proposed constraint compared with that under the conventional interference por constraint.
