Through OFDM, an effective and low complexity technique of eliminating inter-symbol interference for transmission over frequency selective fading channels can be obtained. This technique of eliminating inter symbol interference has a wide area of interest in mobile communication research as the radio channel is usually frequency selective and time variant. Channel estimation information can be reliably estimated by transmitting pilot carriers along with data symbols. In this paper, the authors investigate the various efficient pilot based channel estimation schemes for MIMO-OFDM systems.
