The aim of this paper is to estimate the Channel characteristics of OFDM communication
system by using worst case H∞ approach and comparing the result with existing Kalman [6]
and H∞ channel estimators [8]. This estimation criterion is different from kalman filter. These
two algorithms fail because of more updation parameters like V, W and Q. In order to estimate
the signal without updating factors, we are proposing this worst case H-infinity approach in
which V and W are considered as worst case values (maximum). In this approach V and W are
updated only once for entire recursive estimation process. This method improves the
performance even for high data rate also.
