Description: —The minimum variance distortionless response
(MVDR) approach is very popular in array processing. It is also
employed in spectral estimation where the Fourier matrix is used
in the optimization process. First, we give a general form of the
MVDR where any unitary matrix can be used to estimate the
spectrum. Second and most importantly, we show how the MVDR
method can be used to estimate the magnitude squared coherence
function, which is very useful in so many applications but so few
methods exist to estimate it. Simulations show that our algorithm
givesmuchmore reliable results than the one based on the popular
Welch’s method. Platform: |

Description: 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. Platform: |
