調適性訊號處理

考慮應用於自適應最小方差無失真響應（MDVR）波束成形器的LMS算法由五個均勻間隔的傳感器的線性陣列組成。 陣列的相鄰元件之間的間隔d等於接收波長λ的一半。 波束形成器在由兩個分量組成的環境中操作：沿著感興趣的方向撞擊陣列的目標信號和來自

未知方向。 假設這兩個分量源自獨立的源，並且接收的信號在每個傳感器的輸出處包括加性白高斯噪聲。-ASP

Consider　the　LMS　algorithm　applied　to　an　adaptive minimum-variance distortionless response (MDVR) beamformer consists of a linear array of five uniformly spaced sensors. The spacing d between adjacent elements of the array equals one-half of the received wavelength  . The beamformer operates in an　environment　that　consists　of　two　components:　a　target　signal　impinging　on　the array along a direction of interest and a single source of interference coming　an

unknown　direction.　It　is　assumed　that　these　two　components　originate　 independent　sources　and　that　the　received　signal　includes　additive　white　Gaussian noise at the output of each sensor.
