摘要
传统的最小二乘法进行MIMO系统信道系数估计的过程中,当信噪比比较低的时候均方误差比较大,文章给出了改进的最小二乘法,能够有效地改善均方误差,提高估计的精度,减少误码率。
In the process of conducting the MIMO system channel square method is adopted traditionally. Under the traditional situation, the the case with a low signal-to-noise ratio. This paper presents an improved effectively improve the mean square error, improve estimation accuracy, and coefficient estimation, the least mean square error is larger in least square method, which can reduce the error rate.
