MIMO Networks with One-Bit ADCs: Receiver Design and Communication Strategies
Abbas Khalili, Farhad Shirani, Elza Erkip +1
High resolution analog to digital converters (ADCs) are conventionally used at the receiver terminals to store an accurate digital representation of the received signal, thereby al…
Cell-Free Massive MIMO with Low-Complexity Hybrid Beamforming
Abbas Khalili, Alexei Ashikhmin, Hong Yang
Cell-Free Massive Multiple-input Multiple-output (mMIMO) consists of many access points (APs) in a coverage area that jointly serve the users. These systems can significantly reduc…
Hybrid Beam Alignment for Multi-Path Channels: A Group Testing Viewpoint
Ozlem Yildiz, Abbas Khalili, Elza Erkip
High-frequency bands such as millimeter-wave and terahertz require narrow beams due to path loss and shadowing. Beam alignment (BA) methods allow the transceivers to adjust the dir…
On Single-User Interactive Beam Alignment in Next Generation Systems: A Deep Learning Viewpoint
Abbas Khalili, Sundeep Rangan, Elza Erkip
Communication in high frequencies such as millimeter wave and terahertz suffer from high path-loss and intense shadowing which necessitates beamforming for reliable data transmissi…
On Single-User Interactive Beam Alignment in Millimeter Wave Systems: Impact of Feedback Delay
Abbas Khalili, Shahram Shahsavari, Mohammad A. Amir Khojastepour +1
Narrow beams are key to wireless communications in millimeter wave frequency bands. Beam alignment (BA) allows the base station (BS) to adjust the direction and width of the beam u…
