Quantized MIMO: Channel Capacity and Spectrospatial Power Distribution
Abbas Khalili, Elza Erkip, Sundeep Rangan
Millimeter wave systems suffer from high power consumption and are constrained to use low resolution quantizers --digital to analog and analog to digital converters (DACs and ADCs)…
Optimal Single-User Interactive Beam Alignment with Feedback Delay
Abbas Khalili, Shahram Shahsavari, Mohammad A. Amir Khojastepour +1
Communication in Millimeter wave (mmWave) band relies on narrow beams due to directionality, high path loss, and shadowing. One can use beam alignment (BA) techniques to find and a…
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…
On Throughput of Millimeter Wave MIMO Systems with Low Resolution ADCs
Abbas Khalili, Shahram Shahsavari, Farhad Shirani +2
Use of low resolution analog to digital converters (ADCs) is an effective way to reduce the high power consumption of millimeter wave (mmWave) receivers. In this paper, a receiver…
On Optimal Multi-user Beam Alignment in Millimeter Wave Wireless Systems
Abbas Khalili, Shahram Shahsavari, Mohammad A. Amir Khojastepour +1
Directional transmission patterns (a.k.a. narrow beams) are the key to wireless communications in millimeter wave (mmWave) frequency bands which suffer from high path loss and seve…
