摘要
本文研究了基于麦克风阵列的组合波束形成器-噪声消除器结构。利用计算机模拟和实验测量对结构的性能进行了评估。通过测量各自组件提供的信噪比改进，研究了波束形成器和消噪器的互操作。提出了一种评估输出信噪比的实验程序:从记录环境中的设定位置捕获所需的信号。噪声信号是从第二个(通常不同的)位置测量的。结果表明，与传统方法相比，该方法的信噪比提高了17 dB
This paper examines microphone-array-based, combined beamformer-noise canceller structures. The performance of the structures is evaluated using computer simulation as well as experimental measurements. The inter-operation of the beamformer and noise canceller is studied by measuring the SNR improvements offered by the respective components. An experimental procedure for evaluating output SNR is presented: the desired signal is captured from a set location in the recording environment. The noise signal is measured from a second (generally different) location. Results reveal an SNR improvement of up to 17 dB, and are compared to those stemming from conventional approaches
