Quadratically Constrained Quadratic Optimal Problem in Robust Relay Networks
Chemical Engineering Transactions, 2016 The paper investigates the problem of a distributed robust relay beamforming in one-way relay networks with imperfect channel state information. The aim is to maximize the SNR (signal-to-noise ratio) of the receiver with the constraint of the total ...

Dual IRS‐Assisted Secure Communication for Untrusted Two‐Way AF Relay Network
IET Communications, Volume 20, Issue 1, January/December 2026.To address the performance loss caused by the difficulty of balancing phase configuration requirements in single‐IRS‐assisted asymmetric bidirectional secure relay communication, this paper proposes a dual‐IRS collaborative optimization framework. Specifically, each user is configured with a dedicated IRS to enable personalized signal reflection, and ...

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.A switched observer design methodology for semilinear parabolic PDEs is developed using adaptive sensor configurations and LMI‐based synthesis conditions. The approach guarantees exponential stability through polynomial parameterization and sum‐of‐squares programming, enabling computationally tractable observer design for infinite‐dimensional systems ...
