A Novel Multiplicative Phase Dithering Scheme for 1-bit Compressive Radar

Abstract: In this paper, we tackle the issue of implementing a dithering procedure for the 1-bit quantization of radar signals that is able to generate high-quality estimates while remaining a low-complexity and cost-efficient solution.

1-bit Compressive Radar with Phase Dithering

Abstract: Dithering techniques, through the addition of a (random) signal before the Analog to Digital Converter (ADC), are widely used in acquisition chain designs for their ability to shape the quantization noise, e.

Quantized Compressive Sensing with RIP Matrices: The Benefit of Dithering

Abstract: Quantized compressive sensing (QCS) deals with the problem of coding compressive measurements of low-complexity signals with quantized, finite precision representations, i.e., a mandatory process involved in any practical sensing model.
