Hi,
 i want to know ,how kalman filter is useful in channel estimation of
MIMO-OFDM system.what key property of kalman filter helps in
estimation.kindly reply soon.

A Kalman filter is a recursive estimator, so it's useful for estimation and/or tracking parameters. I'll let you think of what "parameters" are useful for MIMO-OFDM, as your homework assignment must be due soon.

..yes sir, it is recursive.but i want to know,how it is different from recursive least square estimation.and i want to use it for channel estimation in MIMO-OFDM.
