Complex-Valued Symmetric Radial Basis Function Network for Beamforming [PDF]
The complex-valued radial basis function (RBF) network proposed by Chen et al. (1994) has found many applications for processing complex-valued signals, in particular, for communication channel equalization and signal detection. This complex-valued RBF network, like many other existing RBF modeling methods, constitutes a black-box approach that seeks ...

WDM-enabled multi-core parallel programmable photonic signal processor [PDF]
As a frontier in integrated photonics, 2D waveguide mesh-based programmable processors offer compact, reconfigurable platforms. However, conventional Mach–Zehnder interferometer (MZI)-based designs rely on wavelength-agnostic routing, which monopolizes ...

Joint beamforming and transmit power control for maximizing uplink communication rate of active IRS-assisted ISAC system [PDF]
Existing studies related to active intelligent reflecting surface (IRS)-assisted integrated sensing and communication (ISAC) systems generally focus on sensing performance optimization in downlink communication scenarios, and there lacks research that ...

Design of far field beamforming problem by window function [PDF]
Abstract The design of the broadband beam former problem is to find the coefficients vector for all FIR filters such that output fits to a given target spatial directivity pattern in a specified domain. This problem is always very complicated. In this paper, we propose a fast window function method to solve this problem.

Precision planter monitoring system based on mobile communication network
Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Cognitive and clinical dysfunction, altered MEG resting-state networks and thalamic atrophy in multiple sclerosis. [PDF]
The relation between pathological findings and clinical and cognitive decline in Multiple Sclerosis remains unclear. Here, we tested the hypothesis that altered functional connectivity could provide a missing link between structural findings, such as ...

Tuning of the functional beamforming resolution for wind tunnel measurements [PDF]
Conventional Frequency Domain Beamforming (CB) is characterised by the frequency dependency of the mainlobe width and by the presence of sidelobes that limit its dynamic range.

MEG can map short and long-term changes in brain activity following deep brain stimulation for chronic pain. [PDF]
Deep brain stimulation (DBS) has been shown to be clinically effective for some forms of treatment-resistant chronic pain, but the precise mechanisms of action are not well understood.

Radio Over Fiber Downlink Design for Spatial Modulation and Multi-Set Space-Time Shift-Keying
Spatial modulation (SM) and multi-set space-time shift-keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained.
