| Abstract: | As a combination of OFDM with space - time coding technique, MIMO - OFDM has recently attracted considerable attentions,which can not only effectively enhance the transmission rate and capacity of the wireless communication system but also effectively combat multi - path fading and interfere. This paper discusses the two - dimensional pilot - based channel estimation method in MIMO - OFDM system, and the principle of choosing of pilot symbol is given. Finally the effectiveness of the algorithms is made by computer simulation. |
