| Abstract: | The rapidly speeding-up noise signal of a vehicle is a kind of short-time non-stationary signal.Based on the various time-frequency analysis techniques,a method is found,suitable for processing the rapidly speeding-up noise signal-short time maximum entropy spectrum method.This is conducive to the further study on rapidly speeding-up noise problem. |
