    • The span of a linear transversal equalizer filter moves according to the current positions of the multi-paths to a receiver. The alignment of the filter span is measured quantitatively with respect to the current positions of the multi-paths. Adjustments are made to the filter span to enable the linear transversal filter to capture most of the available energy of the transmitted signal. The low-pass-filtered magnitudes of tap weights of the linear filter are multiplied with values of a function which has zeroes at desired points for the larger tap weights, and a gradient of the function at its zeroes being non-zero. The magnitude of the alignment measurement signal is used as a quantitative measure of the alignment of the equalizer span, while the sign of the alignment measurement signal can be used to decide the direction that the span should be moved in.
    • 线性横向均衡器滤波器的跨度根据多路径的当前位置移动到接收器。 相对于多路径的当前位置,定量地测量滤波器跨度的对准。 对滤波器范围进行调整,以使线性横向滤波器捕获传输信号的大部分可用能量。 线性滤波器的抽头权重的低通滤波幅度与在较大抽头权重的期望点处具有零的函数的值相乘,并且其零点处的函数的梯度为非零。 对准测量信号的大小用作均衡器跨度的对准的定量测量,而对准测量信号的符号可用于确定跨度应该移动的方向。
