Gossip Algorithms for Distributed Signal Processing [PDF]
Proceedings of the IEEE, 2010 Gossip algorithms are attractive for in-network processing in sensor networks because they do not require any specialized routing, there is no bottleneck or single point of failure, and they are robust to unreliable wireless network conditions. Recently,

A note on the trade-off between sampling and quantization in signal processing
Journal of Complexity, 1987 AbstractWe discuss the trade-off between sampling and quantization in signal processing for the purpose of minimizing the error of the reconstructed signal subject to the constraint that the digitized signal fits in a given amount of memory. For signals with different regularities, we estimate the intrinsic errors from finite sampling and quantization,

Signal Quantization Effects on Acquisition Process of GPS Receiver: The Analysis and Simulation
2008 Congress on Image and Signal Processing, 2008 Signal quantization levels can have significant impact on the performance of a GPS receiver, especially in the present of the interference. In this paper, signal quantization model for estimating interference suppression of the correlator output and evaluating the performance of GPS receiver is presented.

Enhanced Multi-Level Phase Quantizer for the Optical Processing of M-PSK Signals
Journal of Lightwave Technology, 2016 This paper presents a novel multi-level phase quantizer with the potential of almost ideal step like transfer function. Its operation relies on the proper combination of phase sensitive amplification in highly nonlinear fibers and amplitude limitation offered by injection locked lasers.

Optimization of Quantized Analog Signal Processing Using Genetic Algorithms and μ-Law
IEEE Open Journal of Circuits and Systems, 2022 Digital mismatch calibration for quantized analog (QA) signal processing is proposed for the first time. Since the proposed calibration mechanism does not require uniform QA slicer levels, non-uniform quantization can be applied to improve the system performance.
