  abstract: Short-time signal analysis is a special tool for adaptive estimation, which estimates time-varying features of non-stationary signals or systems by using a slidingwindow to localize the data, then applying stationary estimation to the localized data to generate a local estimate. Short-time signal analysis is a fundamental problem involved in adaptive signal processing, such as adaptive filtering, adaptive system identification, time-frequency/time-scale(wavelet) analysis, filter bank design, etc. Recursive short-time signal analysis is an efficient method to implement the short-time signal analysis, which estimates a local feature at a new time by updating those previously obtained ones with a new coming data. Windows suitable for this recursive implementation, called recursive windows, are very limited. Efficient recursive windows with desirable properties are highly demanded, especially for real-time processing. A rigorous definition of short-time signal analysis is given in Chapter II. Chapters III through VIII constitute the kernel part of this dissertation, in which a set of recursive windows and corresponding recursive procedures for short-time signal analysis are developed. These recursive windows include real-pole windows, complexpole windows, a cosine-wave window, and a half-sine-wave window. The structures, properties, and design procedures of these windows are carefully investigated. The recursive procedure of short-time signal analysis corresponding to each of these windows is derived in detail. The efficiencies of these procedures are also discussed. It is shown that complex-pole windows require exactly the same computation as the real-pole windows of the same order while their shapes are more desirable, implying better estimation is obtained at no cost. The recursive cosine-wave window and half-sine-wave window are bell-shaped: absolutely symmetric, single-peaked, and smoothly tapered off, therefore are among the ideal windows. The cosine-wave window a…
