Jointly optimal array geometries and waveforms in active sensing: New insights into array design via the Cramér-Rao bound Open
This paper investigates jointly optimal array geometry and waveform designs for active sensing. Specifically, we focus on minimizing the Cramér-Rao lower bound (CRB) of the angle of a single target in white Gaussian noise. We first find th…

Optimal Pilot Design for OTFS in Linear Time-Varying Channels Open
This paper investigates the positioning of the pilot symbols, as well as the power distribution between the pilot and the communication symbols in the orthogonal time frequency space (OTFS) modulation scheme. We analyze the pilot placement…

Doppler-tolerant underwater communications Open
Underwater communication is vital for applications like environmental monitoring, marine exploration, and underwater robotics. Real-time communication from autonomous underwater vehicles (AUVs) or bottom nodes to a gateway buoy faces limit…

Measurement Light Bulb: Power distribution, motors and construction Open
This document describes the design process the prototype of a measurement light bulb which is able to project spherical harmonics of orders 0-1-2. Photographs of these projections can be combined to represent many light distributions. The …
