Path Selection‐Based Beamforming Design for RIS‐Aided mmWave Massive MIMO Systems
This paper investigates the beamforming design for reconfigurable intelligent surface (RIS)‐aided millimetre‐wave (mmWave) massive MIMO systems. The key idea is a subspace‐oriented dominant path selection strategy that explicitly accounts for inter‐path correlation and improves the conditioning of the resulting reduced‐dimensional effective channel ...

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM
This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

The integration of reconfigurable intelligent surfaces (RIS) into multiple‐input multiple‐output (MIMO) systems offers transformative potential for enhancing spectral efficiency and mitigating channel impairments. However, efficient and accurate channel estimation (CE) remains a critical challenge due to multipath propagation, high dimensionality, and ...

Hybrid Precoding Design for MIMO System With One-Bit ADC Receivers
When wireless transmission is performed over the bandwidth in the order of a gigahertz, high-resolution analog-to-digital converters (ADCs), and the large number of radio frequency chains significantly increase the power consumption.
