| Abstract: | Reduced-rank least square channel estimation algorithm improves conventional least square of the pulse response of a communication channel. In this paper, the authors present the quantitative statistical analysis of the mean-squared error performance of the algorithm. An approximate expression for the mean-squared error of the algorithm is given. Simulation results have confirmed the validity of the theory in this paper. |
