Output Feedback Model Predictive Control for NCSs with Input Quantization
Complexity, 2022 This paper addresses the robust output feedback model predictive control (MPC) schemes for networked control systems (NCSs) with input quantization. The logarithmic quantizer is considered in this paper, and the sector bound approach is applied, which ...

Quantized Feedback Control of Active Suspension Systems Based on Event Trigger
Shock and Vibration, 2021 As the deviation error will accumulate during the data acquisition and transcoding process of an active suspension system, this paper presents a sliding-mode-based quantized feedback control method.

Vector channel capacity with quantized feedback [PDF]
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005 We explore the capacity of an isotropic fading vector channel with multiple transmit antennas at the base station and a single antenna at the mobile receiver. Perfect channel knowledge is assumed to he available at the receiver while the transmitter has only partial knowledge of the direction of the user's channel vector based on quantized feedback. We

A Second-Order Single Loop Oversampling Analog-to-Digital Converter (ADC) with Proposed Hybrid Feedforward/Feedback Architecture [PDF]
Engineering and Technology Journal, 2012 This paper proposes hybrid architecture of feedforward/feedback second order single-loop modulator for high resolution analog-to-digital converter (ADC) applications. Different techniques for oversampling modulator are discussed.

Quantized current source with mesoscopic feedback [PDF]
Physical Review B, 2011 We study a mesoscopic circuit of two quantized current sources, realized by non-adiabatic single- electron pumps connected in series with a small micron-sized island in between. We find that quantum transport through the second pump can be locked onto the quantized current of the first one by a feedback due to charging of the mesoscopic island. This is

Learning Physical-Layer Communication With Quantized Feedback [PDF]
IEEE Transactions on Communications, 2020 Data-driven optimization of transmitters and receivers can reveal new modulation and detection schemes and enable physical-layer communication over unknown channels. Previous work has shown that practical implementations of this approach require a feedback signal from the receiver to the transmitter.

A Control Structure for Unilateral System with Communication Rate Constraint
SICE Journal of Control, Measurement, and System Integration, 2018 This study proposes a design method for unilateral control systems with communication rate constraints. In the case where it is necessary to control under a communication rate constraint, the effect of the quantization noise should be minimized using ...

Feedback quantization in crosscorrelation predistorters [PDF]
IEEE Microwave and Wireless Components Letters, 2005 Amplification of signals with fluctuating envelopes inevitably leads to distortion because of non-linear behavior of the Power Amplifier (PA). Digital Predistortion can counteract these non-linear effects. In this paper, the crosscorrelation predistorter is described and the effects of quantization in the feedback path are presented. One of the effects
