1、 An Introduction To Compressive Sampling Candes E.J. Wakin M.B. IEEE Signal Processing Magazine 应该没人敢说这个不是顶刊了吧 传统的信号或图像采样方法遵循香农的著名定理:采样率必须至少是信号中存在的最高频率的两倍(所谓的奈奎斯特率)。例如,在数据转换领域,标准的模拟-数字转换器(ADC)技术实施了常规...
3.2.3Compressive sensing Compressive Sensing(CS) refers to a sensing scheme in which perceived signals are compressed at the time of sensing, which allows for reliable sampling at a lower rate than the Nyquist rate[92]. This is only plausible if the sensed signal is sparse and compressible, ...
The concept of fault was presented in the introduction to this section, but it must be considered that faults can present themselves in different ways in a system and are therefore classified accordingly. Considering the different pieces of equipment that compose an engineering system, such as contr...
Introduction The keen tactile sensing of humans relies on numerous mechanoreceptors that can detect pressure in a wide range (up to 300 kPa) with a low detection limit (down to 1 Pa)1,2,3,4. In robotics, the achievement of dexterity of robots demands high-performance flexible sensors ...
Instrumented implants are being developed with a radically innovative design to significantly reduce revision surgeries. Although bone replacements are among the most prevalent surgeries performed worldwide, implant failure rate usually surpasses 10%. Hi
Xu et al. [15] propose a novel hierarchical data aggregation method using compressive sensing which combines a hierarchical network configuration. Their key idea is to set multiple compression thresholds adaptively based on cluster sizes at different levels of the data aggregation tree to optimize the...
Rongqing Hui, in Introduction to Fiber-Optic Communications, 2020 Introduction Photodetector is the key device in the front end of an optical receiver that converts the incoming optical signal into an electrical signal, known as O/E convertor. Semiconductor photodetectors, commonly referred to as pho...
