The estimation algorithm is developed in our Laboratory and the experiment is done by Nissan Motor Corporation. Based on Wavelet Analysis Wavelet transform can analyze a signal's characteristic efficiently in time-frequency domain. It helps us to develop some advanced applications of estimation, identification and control. For example, we developed an estimation algorithm of tire's pressure and a control algorithm for automobile's automatic transmissions. On the other hands, wavelet analysis makes it easy to detect singularity, discontinuity and self-similarity of a signal.
