摘要
文中介绍了一种新算法——LWVD,即通过局域波分解复杂信号,得到有限个基本的模式分量,然后计算Wigner-Ville分布。这种方法有效地抑制了时频分布交叉项的干扰。通过仿真试验,验证了这种方法的有效性。
This paper presents a new method-LWVD: by decomposing complex signals using the local wave method, several intrinsic-mode functions are obtained, and Wigner-Ville distribution is then computed. This method can suppress the cross-term interference of time-frequency distribution. Simulation tests show that the method is effective.
