THE OPTIMAL WINDOW FUNCTIONS OF SHORT TIME FOURIER TRANSFORM AND PSEUDO-WIGNER DISTRIBUTION
短时傅里叶变换和拟Wigner分布最佳窗函数

Short time Fourier transform and pseudo-Wigner distribution are two most useful tools in time-frequency analysis, the choice of window functions is the base for their applications, which require deep study. The criteria of window functions are discussed in detail, and the optimal length of window is obtained by means of optimal frequency resolutions.
