Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The antenna subarray formation (ASF) is a promising technique for multiple-input multiple-output (MIMO) receiver. For MIMO cognitive radio systems,  propose a joint beamforming and ASF scheme in this letter which maximizes the cognitive achievable capacity subject to the peak transmit por constraint at the secondary transmitter, peak interference por constraint at the primary receiver, and the limited number of nonzero elements in the ASF matrix. To solve the joint optimization problem,  propose a relax-and-recover scheme. Simulation results have shown that the proposed scheme outperforms the conventional antenna selection scheme.
