离散分数阶傅里叶变换，可以处理非平稳信号，也可以很好的对抗多普勒频移，用在OFDM系统中尤为重要。-Discrete fractional Fourier transform, can handle non-stationary signal can also be very good against the Doppler frequency shift, used in the OFDM system is particularly important.

TFBSS是一种基于短时傅里叶时频分析的盲源分离算法，算法基于卷积混合。处理非平稳源信号。-TFBSS performs Blind Source Separation of (over)determined multiplicative mixtures of non-stationary real valued sources. TFBSS is based on the joint-diagonalization of whitened and noise-compensated
