摘要：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
