A Constrained Deep Reinforcement Learning Framework for Beamforming Optimization With QoS Guarantees in RIS‐Assisted Symbiotic Radio Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
To address the complex constrained optimization in time‐varying reconfigurable intelligent surface–assisted symbiotic radio networks, this paper proposes a novel deep reinforcement learning (DRL) approach integrating Lagrange dual optimization into deep deterministic policy gradient framework.

Performance Analysis of Directional Modulation With Finite-Quantized RF Phase Shifters in Analog Beamforming Structure

IEEE Access, 2019
The radio frequency (RF) phase shifter with finite quantization bits in analog beamforming (AB) structure forms quantization error (QE) and causes a performance loss of received signal to interference plus noise ratio (SINR) at the receiver (called Bob).

Computationally Efficient Deep Learning Inference for High‐Rate Beamforming in Millimeter‐Wave Internet of Vehicles

IET Communications, Volume 20, Issue 1, January/December 2026.
ABSTRACT Millimeter‐wave (mmWave) Internet‐of‐Vehicles (IoV) communications rely on large antenna arrays to combat severe path loss and to provide high beamforming gains. However, practical vehicular deployments often adopt analog or hybrid beamforming with constant‐modulus constraints, leading to a highly non‐convex joint beamforming design problem ...

Cognitive GFDM Full-Duplex Radios With RF Impairments and ACI Constraints

IEEE Open Journal of the Communications Society, 2020
We investigate the problem of sum-rate maximization of a secondary link of full-duplex generalized frequency division multiplexing (GFDM) radios operating over a spectrum hole, which is surrounded by two active primary adjacent channels.
