出于准确的宽带导向矢量的应用，如宽带到达角估计的要求，我们审查分数延迟滤波器的设计。它们的一个共同特点是，当接近奈奎斯特速率时，性能迅速下降。我们提出了一种基于滤波器组的方法，该方法在一系列频移子带信号上操作标准分数延迟滤波器，使得它们出现在滤波器的低通区域中。我们在模拟中展示了这种方法的吸引力。
Motivated by accurate broadband steering vector requirements for applications such as broadband angle of arrival estimation, we review fractional delay filter designs. A common feature across these are their rapidly decreasing performance as the Nyquist rate is approached. We propose a filter bank based approach, which operates standard fractional delay filters on a series of frequency-shifted subband signals, such that they appear in the filters' lowpass region. We demonstrate the appeal of this approach in simulations.
