Abstract :
In this paper, a whitening-rotation (WR)-based semi-blind channel estimation method for a multiple input multiple output (MIMO) wireless communication system is investigated. The relationship between the estimation accuracy and the channel properties is analyzed. It is shown that the channel estimation minimum square error (MSE) of the investigated semi-blind estimation scheme is dependent on the sum of eigenvalues of the channel auto-correlation matrix. The computer simulations support this conclusion.
