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…
Beam Entropy of 5G Cellular Millimetre-Wave Channels
Krishan Kumar Tiwari, Eckhard Grass, John S. Thompson +1
In this paper, we obtain and study typical beam entropy values for millimetre wave (mm-wave) channel models using the NYUSIM simulator for frequencies up to 100 GHz for fifth gener…
Memory-assisted Statistically-ranked RF Beam Training Algorithm for Sparse MIMO
Krishan K. Tiwari, Eckhard Grass, John S. Thompson +1
This paper presents a novel radio frequency (RF) beam training algorithm for sparse multiple input multiple output (MIMO) channels using unitary RF beamforming codebooks at transmi…
