Adaptive signal deconvolution problem is reviewed by the new view point of the time series analysis. For unknown signal described by unknown multivariable sta-tionary ARMA model, and observed through a known multivariable linear system, based on ARMA innovation model, using the time series analysis method and the pro-jection theory, this paper presents a new optimal deconvolution smoother and the cor-responding self-tuning deconvolution smoother, that is different from Goodwin and Sin's result which is based on the state -speace model. A simulation example is given to show the usefulness of results proposed. The results of this paper involve many problem and results in references as special cases, and can be applied to seismic deconvolution, signal processing, communication, speech identification and other fields.

To detect unknown signals,we usually use the generalized likelihood ration test(GLRT).However,the performance of the GLRT is not very good since it does not adequately use the intrinsic characteristic of transients.By introducing the wavelet transform property of transients and noise, this paper presents one method based on the estimation in wavelet tranform domain(EWD).Finally,a comparison between the receiver operating characteristics(ROC)of several detectors is made.
