Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  propose an optimal and a suboptimal resource allocation algorithms for sum rate maximization in an MISO-OFDMA based cognitive radio network subject to a primary user outage constraint. By converting the outage constraint into user and subcarrier dependent peak por constraints,  obtain the optimal joint subcarrier assignment and por allocation solution by applying Lagrange dual-decomposition method.  also propose a low-complexity, fast-convergent suboptimal algorithm which uses an opportunistic channel gain-to-noise ratio based subcarrier assignment and an efficient constrained por allocation scheme. The optimality of the latter por allocation scheme is verified as ll. Numerical results demonstrate that, compared with the optimal solution, the suboptimal scheme suffers only minor performance loss.  also shown that the use of more transmit antennas by a cognitive base station not only yields better spectrum efficiency but also lessens the outage-induced peak por constraint.
