Noise-shaping Quantization Methods for Frame-based and Compressive Sampling Systems

Understand

Noise shaping refers to an analog-to-digital conversion methodology in which quantization error is arranged to lie mostly outside the signal spectrum by means of oversampling and feedback.

• Recently it has been successfully applied to more general redundant linear sampling and reconstruction systems associated with frames as well as non-linear systems associated with compressive sampling.
• This chapter reviews some of the recent progress in this subject.
