| dc.description.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 exploiting pilot from preamble, in this paper we obtain channel transfer function by exploiting pilot at symbol data with two dimensial interpolation scheme. Based on our simulation, it can be shown that the proposed method have better performance compare with preamble based channel estimation method. Afterwards we compare Linear Interpolation and MMSE interpolation for proposed channel estimation method. The Symbol Error Rate for QPSK and 64 QAM system is presented by means of simulation. | en_US |
