The method of channel estimation adopted in a MIMO-OFDM communication system greatly influences the overall performance of the system. The symbol detection is carried out after reversing the influences of channel on the information. Hence, the technique used for channel estimation is as important as channel prediction. Under fast time varying channel conditions the channel characteristics need to be accurately extracted using both channel estimation and prediction. An effort is made to emphasize the various techniques developed in literature tending to precisely obtain the channel characteristics. The channel estimation methods specifically designed for the demanding channel conditions having fast time varying characters are separately emphasized.
