Abstract
The research topics investigated were primarily in the areas of quantization and detection in signal processing. The existence of optimal quantizers was established under very general conditions and convergence properties of sequences of quantizers to optimal quantizers were investigated. A simple and straightforward technique was presented for constructing minimum mean-squared error symmetric uniform scalar quantizers for some common input distributions. THe Lloyd-Max algorithm was modified to give a very fast design algorithm for scalar minimum mean-squared error quantization. In the area of detection, a continuous time filter was designed for a discrete time problem and outperformed the corresponding discrete time detector. Detection problems were investigated when both signal and noise were modelled as phi-mixing random processes. Several situations were investigated in which asymptotic relative efficiency is an inappropriate measure of efficiency. In a different area of research, the effects of a form of nonlinear distortion on spectral properties of random processes were investigated. (Author)
