Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Cognitive radio requires por spectral density (PSD) estimation in order to detect the inactive bands for opportunistic secondary usage. ,  present a new compressed por spectral estimation scheme via group-based total variation minimization. Leveraging the intra-group total variation penalty, piecewise-constant characteristics in the signal por spectrum are modeled to improve accuracy of estimation. The effectiveness of the proposed technique is illustrated using simulation of complex baseband OFDM signals. The results show that the proposed scheme has lor por spectral estimation error at the same compressed sampling rate and signal-to-noise ratio compared to previous state of the art compressive spectrum sensing methods.
