Reconfigurable Intelligent Surfaces Assisted Communication Under Different CSI Assumptions
Bayan Al-Nahhas, Qurrat-UI-Ain Nadeem, Aryan Kaushik +1
This work studies the net sum-rate performance of a distributed reconfigurable intelligent surfaces (RISs)-assisted multi-user multiple-input-single-output (MISO) downlink communic…
Millimeter Wave Channel Estimation for Lens based Hybrid MIMO with Low Resolution ADCs
Evangelos Vlachos, Aryan Kaushik, Muhammad Z. Shakir
The high path loss associated with millimeter wave (mmWave) frequency communication can be compensated by large scale antenna arrays such as multiple-input multiple-output (MIMO) s…
Flexible Hybrid Beamforming for Spectrally Efficient 6G Joint Radar-Communications
Aryan Kaushik, Evangelos Vlachos, Muhammad Z. Shakir +2
Joint radar-communications (JRC) benefits from multi-functionality of radar and communication operations using same hardware and radio frequency (RF) spectrum resources. Thus JRC s…
