例句与用法

1. Estimation of covariance matrices
   协方差矩阵的估计
2. Under ideal conditions , adaptive array signal processing methods can get excellent performance and adaptive beamformers provide an improvement in array output signal - to - interference - plus - noise - ratio ( sinr ) in comparison with conventional beamforming . in practical operating circumstances , the performance of adaptive array signal processing methods degrade extremely due to existing errors
   但是，在实际系统中总存在有误差，包括自适应训练样本有限次快拍引起的协方差矩阵的估计误差和各种系统误差，误差使得实际阵列流形与理想阵列流形存在差异，这时自适应阵列信号处理的性能会急剧下降。
