摘要
降秩最小二乘通道估计算法有效地改进了通常的最小二乘对通信通道脉冲响应的估计,本文中我们对此算法的估计均方误差性能进行了定量的分析,文中给出了算法估计的均方误差的近似表达式。模拟实验结果验证了文中理论的正确性。
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.
