通过验证，所产生的调制信号具有良好的误差向量幅度（EVM）和频谱特征。

The algorithm is verified by experiments and the modulator can produce digital modulation signals with good EVM(Error Vector Magnitude) and spectrum mask.

根据相干分布源的近似模型可知，在小角度扩展情况下，角度扩展主要影响广义方向向量各元素的幅度。

Based on specially array geometry designation, the angular spread could be estimated by substituting the estimated DOA into the amplitude information vector.

然后针对每个传感器，根据其各频率波束形成加权向量，采用约束优化方法，设计出具有要求幅度和相位响应的FIR滤波器。

Then, the BCBB is implemented by a set of FIR filters corresponding to the input channels, which provides the frequency response derived from BCBB weights for each sensor.
