# Signal Processing and Piecewise Convex Estimation

@article{Riedel1996SignalPA, title={Signal Processing and Piecewise Convex Estimation}, author={Kurt S. Riedel}, journal={arXiv: Methodology}, year={1996} }

Many problems on signal processing reduce to nonparametric function estimation. We propose a new methodology, piecewise convex fitting (PCF), and give a two-stage adaptive estimate. In the first stage, the number and location of the change points is estimated using strong smoothing. In the second stage, a constrained smoothing spline fit is performed with the smoothing level chosen to minimize the MSE. The imposed constraint is that a single change point occurs in a region about each empirical…

Complex demodulation of evolutionary spectra is formulated as a two-dimensional kernel smoother in the time-frequency domain, where the optimal taper length is a small fraction of the optimal kernel halfwidth and the ratio of the ideal-frequency halfwidth to the optimal-time halfwidth is determined.
