A Survey on mmWave Channel Attenuation and mMIMO Beamforming for Future Wireless Networks

Millimeter-wave (mmWave) communication and massive multiple-input multiple-output (mMIMO) are widely used in 5G and are expected to remain important for future wireless systems. mmWave provides large bandwidth and can deliver very high data rates. mMIMO relies on large antenna ar...

LSTM-Based Spectrum Sensing for Improved Detection in Low-SNR Cognitive Radio Networks

Spectrum sensing is the first step in cognitive radio systems; before transmitting, a secondary user must confirm that a licensed channel is truly free. The classical energy detector is used as a baseline in this work, and it is improved by reconsidering the way the decision thre...

Impact of Wind-Induced Phase-Shift Errors on RIS-Assisted Cell-Free Massive MIMO Networks: Spectral and Energy-Efficiency Analysis

Reconfigurable intelligent surfaces (RISs) can improve spectral efficiency (SE) and energy efficiency (EE) in cell-free massive multiple-input multiple-output (CF-mMIMO) networks by coherently controlling reflected propagation paths. Outdoor panels, however, can experience wind-d...
