Exact expression for the linear canonical Wigner distribution's variance of deterministic signals added with stationary white circular Gaussian noise is derived. It is shown that only one of the linear canonical transform free parameters, the parameter b, affects the value of variance.

线性规范Wigner分布的方差分析

推导了确定性信号与固定的白色圆形高斯噪声相加后的线性规范Wigner分布方差的精确表达式。结果表明，只有线性典范变换自由参数之一参数b会影响方差值。
