Abstract :
As a combination of OFDM with space-time coding technique, MIMO-OFDM has recently received 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 for choices of pilot symbol is given. Finally the effectiveness of the algorithms is made by computer simulation.
