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…
Energy Efficiency Maximization in Millimeter Wave Hybrid MIMO Systems for 5G and Beyond
Aryan Kaushik, John Thompson, Evangelos Vlachos
At millimeter wave (mmWave) frequencies, the higher cost and power consumption of hardware components in multiple-input multiple output (MIMO) systems do not allow beamforming enti…
Joint Bit Allocation and Hybrid Beamforming Optimization for Energy Efficient Millimeter Wave MIMO Systems
Aryan Kaushik, Evangelos Vlachos, Christos Tsinos +2
In this paper, we aim to design highly energy efficient end-to-end communication for millimeter wave multiple-input multiple-output systems. This is done by jointly optimizing the…
Energy Efficient ADC Bit Allocation and Hybrid Combining for Millimeter Wave MIMO Systems
Aryan Kaushik, Christos Tsinos, Evangelos Vlachos +1
Low resolution analog-to-digital converters (ADCs) can be employed to improve the energy efficiency (EE) of a wireless receiver since the power consumption of each ADC is exponenti…
