Signal Breaker: Fuzzing Digital Signal Processors
… fuzzing has yet to make its way to Digital Signal Processor (DSP) software. DSPs sit at the border between hardware and software systems: they transform analog signals external to a system into digital signals for internal processing. Many important societal applications including …

Signal Encoding and Digital Signal Processing in Continuous Time
This work investigates signal encoding in, and architectures of, digital signal processing systems that function in continuous time (CT). Unlike conventional digital signal processors (DSPs), which rely on a clock to dictate the sampling times of an analog-to-digital converter (ADC) and to provide …

Improving Signal Clarity through Interference Suppression and Emergent Signal Detection
… of these applications is to detect or extract a signal of interest. This task is complicated by the presence of interferers and noise, which corrupts the recorded array signals. This dissertation explores two new techniques that increase signal clarity: interferer suppression and emergent signal …

Robust Adaptive Signal Processors
Standard open loop linear adaptive signal processing algorithms derived from the least squares minimization criterion require estimates of the N-dimensional input interference and noise statistics. Often, estimated statistics are biased by contaminant data (such as outliers and non-stationary data) …
