Sobolev Duals for Random Frames and Sigma-Delta Quantization of Compressed Sensing Measurements
S. Güntürk, A. Powell, R. Saab +1
Quantization of compressed sensing measurements is typically justified by the robust recovery results of Candès, Romberg and Tao, and of Donoho. These results guarantee that if a u…

An Optimal Family of Exponentially Accurate One-Bit Sigma-Delta Quantization Schemes
Percy Deift, C. Sinan Güntürk, Felix Krahmer
Sigma-Delta modulation is a popular method for analog-to-digital conversion of bandlimited signals that employs coarse quantization coupled with oversampling. The standard mathemat…
