摘要
针对阵列协方差矩阵特征值分布的特点,从理论上分析了频率扩展对软件天线自适应算法性能的影响,并以MMSE算法为例进行仿真验证.最后对考虑频率扩展时软件天线算法的选择问题进行了讨论.
According to the characteristic of eigenvalue distribution of array covariance matrix, theoretically analyzes the effect of frequency extension on self-adaptation algorithms of software antenna, then takes MMSE algorithm as an example to make an imitation test. At last, discusses the algorithm selection of software antenna according to frequency extension.
