一、概念
英文名称:white Gaussian noise WGN
定义:均匀分布于给定频带上的高斯噪声;
所谓高斯白噪声中的高斯是指概率分布是正态函数,而白噪声是指它的二阶矩不相关,一阶矩为常数,是指先后信号在时间上的相关性。这是考察一个信号的两个不同方面的问题。
高斯白噪声:如果一个噪声,它的幅度服从高斯分布,而它的功率谱密度又是均匀分布的,则称它为高斯白噪声。
热噪声和散粒噪声是高斯白噪声。
二、matlab举例
Matlab有两个函数可以产生高斯

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
