Blind SNR Estimation and Nonparametric Channel Denoising in Multi-Antenna mmWave Systems
Alexandra Gallyas-Sanhueza, Christoph Studer
We propose blind estimators for the average noise power, receive signal power, signal-to-noise ratio (SNR), and mean-square error (MSE), suitable for multi-antenna millimeter wave…
Analog vs. Digital Spatial Transforms: A Throughput, Power, and Area Comparison
Zephan M. Enciso, Seyed Hadi Mirfarshbafan, Oscar Castañeda +3
Spatial linear transforms that process multiple parallel analog signals to simplify downstream signal processing find widespread use in multi-antenna communication systems, machine…
Algorithm and VLSI Design for 1-bit Data Detection in Massive MIMO-OFDM
Seyed Hadi Mirfarshbafan, Mahdi Shabany, Seyed Alireza Nezamalhosseini +1
The use of low-resolution data converters in the radio-frequency (RF) chains of all-digital massive multiple-input multiple-output (MIMO) basestations promises significant reductio…
CSI-Based Multi-Antenna and Multi-Point Indoor Positioning Using Probability Fusion
Emre Gönültaş, Eric Lei, Jack Langerman +2
Channel state information (CSI)-based fingerprinting via neural networks (NNs) is a promising approach to enable accurate indoor and outdoor positioning of user equipments (UEs), e…
Optimal Data Detection and Signal Estimation in Systems with Input Noise
Ramina Ghods, Charles Jeon, Arian Maleki +1
Practical systems often suffer from hardware impairments that already appear during signal generation. Despite the limiting effect of such input-noise impairments on signal process…
Identifying Unused RF Channels Using Least Matching Pursuit
Emre Gönültaş, Milad Taghavi, Sweta Soni +2
Cognitive radio aims at identifying unused radio-frequency (RF) bands with the goal of re-using them opportunistically for other services. While compressive sensing (CS) has been u…
