英文摘要 | Cohen's bilinear time-frequency distribution has received considerable attention as a powerful tool for analyzing nonstationary signals. In this paper, a new discrete-time time-frequency distribution is introduced. Unlike the existing analytic signal method, the new one utilizes all signal local autocorrelation information, so that, without computing analytic signal, one can avoid aliasing when the signal is sampled at one Nyquist's rate. Some desirable distribution properties and associated kernel requirements are also discussed.; EI; 0; 1; 112-118; 35 |
