The intention of this paper is to review the work that has been already done in the field of channel estimation in MIMO-OFDM system. With the continuous growth and the improvement of communication system, our aim is to review the current best techniques available for channel estimation and provide a comparative analysis. In order to achieve this objective, a simulation has been performed for using various channel estimation techniques. The main emphasis is laid on selection of a channel through which the signals are to be transmitted. This paper reviews the different types of channel estimation in MIMO system by varying the precoding and modulation techniques.
