MMSE‐based passive beamforming for reconfigurable intelligent surface aided millimeter wave MIMO

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
Passive beamforming at reconfigurable intelligent surface (RIS) in RIS‐aided millimeter wave multiple‐input multiple‐output (mmWave MIMO) is designed together with precoder and combiner through joint optimization problem to minimize the mean square error between the transmit signal and the estimate of signal at the receiver. The optimization problem is

A squeeze‐and‐excitation network for SNR estimation of communication signals

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
This paper presents a novel deep learning approach that uses a power spectrum generated through overlapping segmentation as input to a neural network for SNR estimation. The performance of SNR estimation has been enhanced by integrating an augmented squeeze‐and‐excitation (SE) attention mechanism with a residual block fusion module, employing multiple ...

A RIS‐Based Single‐Channel Direction‐of‐Arrival Estimation Method for Communication Signals

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
This paper proposes a reconfigurable intelligent surface (RIS)‐based single‐channel direction‐of‐arrival (DOA) estimation method for communication signals. Our method, which incorporates RIS, extended time intervals, atomic norm minimization (‐alternating direction method of multipliers, and mutual incoherence property, addresses the two main problems:

A Novel FBMC/QAM Scheme to Eliminate the Error Floor in Multipath Channels

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
This paper proposes a cyclic prefix–based filter bank multicarrier with quadrature amplitude modulation (CP‐FBMC/QAM) scheme to eliminate the error floor and simplify the receiver in multipath fading channels. Moreover, to avoid the increase of out‐of‐band (OOB) radiation caused by the CP insertion, we propose a prototype filter optimization problem ...

Performance Analysis for Reconfigurable Intelligent Surface‐Aided Cache‐Enabled Wireless Networks

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
We consider a downlink RIS‐aided, cache‐enabled network from Figure 1, and we have investigated and analysed the performance of RIS‐aided cache‐enabled wireless communication system. ABSTRACT Locally caching at base stations (BSs) can increase the network capacity as well as reduce the backhaul burden.
