Reports

Technical reports written during my graduate years, transcribed from their original PDFs with rendered LaTeX and adapted as self-contained tutorials — figures and experimental results have largely been omitted so each stands on its own.

• Generalized Digital Modulation and IF Modulation — a chirplet view of digital modulation, with emphasis on instantaneous-frequency (IF) modulation.
• Wavelet Packets and Signal-Adapted Filter Banks — signal-adapted bases via principal component filter banks, compaction filters, and wavelet packets.
• Architecture for Distributed Source Localization in Wireless Sensor Networks — a cross-layer ad-hoc protocol with a self-organizing MAC for collaborative source localization.
• Space-Frequency Coded OFDM — Alamouti coding across OFDM sub-carriers for frequency-selective fading channels.
• An Empirical Bayesian Kernel Density Estimator — a multiscale, rank-adapted kernel density estimator with hierarchical priors and Gibbs sampling.
• Joint Estimation in Dynamic State-Space Models — rolling-window Sequential Monte Carlo (FFBS) for jointly estimating states and static parameters in a dynamic state-space model.
