Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Advanced Electronic Materials, EarlyView.Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Navigation in multipath environments for suburban applications [PDF]
, 2007 In 2002 the German Aerospace Centre (DLR) performed a measurement campaign of the land mobile multipath channel. From this data a channel model was derived that is synthesising the measured channel impulse response. It allows the realistic simulation

Closed-form inverses for the mixed pixel/multipath interference problem in AMCW lidar [PDF]
, 2012 We present two new closed-form methods for mixed pixel/multipath interference separation in AMCW lidar systems. The mixed pixel/multipath interference problem arises from the violation of a standard range-imaging assumption that each pixel integrates ...

A Robust Receiver Based on Chaos Modulation for the Industrial Internet of Things
IEEE Access, 2021 Industrial wireless channels feature rich multipath components and strong noise. Massively deployed nodes in an industrial network are often cheap devices. Under such circumstances, the received packets are prone to errors.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Effect of Multipath on Code-Tracking Error Jitter of a Delay Locked Loop [PDF]
, 2009 It is very well known that multipath propagation is a major source of error for code and carrier phase measurement performed by a GNSS receiver. The presence of multiple reflections confounds the receiver and the estimation of the time delay will carry a

Understanding and Ameliorating Non-Linear Phase and Amplitude Responses in AMCW Lidar
Remote Sensing, 2011 Amplitude modulated continuous wave (AMCW) lidar systems commonly suffer from non-linear phase and amplitude responses due to a number of known factors such as aliasing and multipath inteference. In order to produce useful range and intensity information
