Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Multiple-input multiple-output MIMO system is a very popular solution in the field of wireless communications, in order to improve the capacity and reliability of radio link. Nevertheless, during any transmission over fading channel, the performance of MIMO system is degraded due to the inter symbol interference ISI. The combination of orthogonal frequency division multiplexing MIMO-OFDM and the use of equalisation at the reception have become very effective to eliminate the ISI and reduce the imperfection of the channel. The optimal maximum likelihood ML equaliser suffers from high computational complexity. In this context,  propose the combination of vertical bell labs space time VBLAST multiplexing and ordered successive interference cancellation OSIC equaliser in MIMO-OFDM system, whose performance is compared with different equalisers, in particular zero forcing ZF, minimum mean square error MMSE, and ML using cyclic prefix CP and zero padding ZP intervals in Rayleigh time-selective fading channel. The simulation results show that the performance of ZF/MMSE-OSIC equaliser with ZP-ODFM is close to the ML with a low complexity and it works better as compared to other algorithms.
