摘要
We have investigated channel estimation with robust pilot symbol and spatial correlation information. Uncorrelative MIMO channel estimation based on ML criterion and pilot design scheme is given in this paper. Since spatial correlation cannot be avoided in real MIMO systems, we present new channel estimation which can make the best of spatial correlation information. The theoretic analysis and simulation results prove that our presented algorithm outperform traditional channel estimation algorithm.
