Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  considers a secondary user (SU) sharing the spectrum licensed to a primary user (PU) if limited interference caused to the latter can be guaranteed. In particular, besides the interference por constraint at the PU to protect the PU, the transmit por of the SU is also considered. Under such a setup,  consider the average bit error rate (BER) as the performance metric for the SU, and then derive the optimal por allocation strategies to achieve the minimum average BER of the SU. Simulation results are presented and discussed. It is shown that the optimal por allocation strategies can achieve substantial performance gain for the SU over the water-filling method.
