Abstract
In this paper, we derive the optimum channel estimation algorithm based on least square (LS) criterion over frequency-selective fading channel in multiple antenna systems. We prove that in order to minimize the mean square error (MSE) of channel estimation over frequency-selective fading channel, the training sequences for the multiple transmit antennas should be ideally cyclically orthogonal in self-correlation and have zero cross-correlation.
