摘要：

A channel estimation method for multiple input multiple output (MIMO)-OFDM with fast fading channels is proposed to increase estimation quality and reduce the computational complexity. Specifically, we use a space-time correlation between channel coefficients, and compensate the 10 term. Since 10 compensation can be obtained without any pilot symbols for target OFDM block, our proposal is practical for real-time systems. The computational complexity is reduced by considering only dominant data symbols.
