摘要: Accurate channel estimation is necessary to gain the advantage of space time coding for decoding purposes. Most previous work on Orthogonal Frequency Division Multiplexed (OFDM) focused single user systems. Hence, they are inappropriate in multiuser communication In this paper, we proposed a novel technique based simple blocked pilot grid Space Time Block Coded (STBC)-OFDM We simulated scheme slowly faded quasi-static channel. LS and MMSE estimator performance different number users also analyzed.
