In this paper we propose a new technique for the pilot assisted power delay estimation for the LMMSE channel estimator for the multiple input and multiple output OFDM system. The distortions due to the null subcarriers and the distortions due to the insufficient samples are also considered. The simulation results show that the proposed PDP estimator gives the good performance in estimating when compared to the weiner filter and kalman filtering.
