Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  proposes an efficient frequency domain interference cancellation algorithm to solve the narrowband interference (NBI) problem for OFDM systems. The multi-tone NBI is estimated, reconstructed and removed from the transmitted signals. To achieve a more accurate estimation of coarse interference frequency, a novel spectrum peak search scheme, which combined with zero padding interpolation, is proposed to avoid the misjudgment of spectral peak position caused by spectrum leakage. The fine estimation of interference frequency is achieved by the modified ighted phase average (WPA) algorithm. Simulation results show that the estimation accuracy of the proposed algorithm is quite close to the Cramer-Rao Lor bound (CRLB) over a wide interference-to-signal ratio (ISR) range and it is robust to different interference frequency intervals.
