Abstract: OFDM Scheme widely used in high data rate communication systems over widest channels. It requires the tracking of the fading radio channel. In this study addresses channel estimation algorithm based on time domain channel statistics. Using a general model for a slowly fading channel, we present the LMMSE based channel estimators. This is mainly used for complexity and improves the performance of the channel.
