In the present scenario, orthogonal frequency division multiplexing (OFDM) systems are greatly utilized in recent multimedia applications and various wireless standards due to their robustness to frequency selective fading channel, high data rate achieving capability, and high spectral efficiency. The multi-input multi-output (MIMO) system in combination with OFDM has drawn significant attention for the next-generation broadband multimedia applications due to the additional potential of providing increased channel capacity. Despite these advantages, one of the major challenges faced in...
