Abstract-High mobility communication systems need suitable channel estimation to cope high frequency selectivity channel effect. in this paper we propose data pilot based channel estimation in downlink OFDMA for IEEE 802.16e standard (Mobile WiMAX). the mobile WiMAX channel estimation can be done by exploting pilot at symbol data with two dimesial interpolation scheme. based on our simulation, it can be shown that the second method have better performance compare with peamble base channel estimation method. the bit error rate and equalized signal scatter plot for 64 QAM system with ITU and ITU B vehicular channel as channel models are presented by means of simulation..
