Zhaohui Liu · Audio Engineering · 2003
According to the features of cross Wigner-Ville distribution(XWVD)between echoes and reference signal,a fast estimation method of parameters of echoes based on XWVD is presented.Com-bined with the time domain correlation,it greatly reduced the computation load while keeping good es-timation performance.Simulation results show the effectiveness of the method.[
