A novel beamformer architecture using fractional delay filters is proposed and verified through experiments. By performing interchannel summation prior to filtering operation in the manner producing no error, the proposed architecture requires only three four-tap filters for the whole beamformer and four simple demultiplexers per each channel.
提出了一种使用分数延迟滤波器的新型波束形成器架构，并通过实验进行了验证。通过以无误差的方式在滤波操作之前执行通道间求和，所提出的架构对于整个波束形成器仅需要三个四抽头滤波器，并且每个通道需要四个简单的解复用器。
