Performance of Analog Beamforming Systems with Optimized Phase Noise Compensation
Vishnu V. Ratnam
Millimeter-wave and Terahertz frequencies, while promising high throughput and abundant spectrum, are highly susceptible to hardware non-idealities like phase-noise, which degrade…

Periodic Analog Channel Estimation Aided Beamforming for Massive MIMO Systems
Vishnu V. Ratnam, Andreas F. Molisch
Analog beamforming is an attractive and cost-effective solution to exploit the benefits of massive multiple-input-multiple-output systems, by requiring only one up/down-conversion…

Continuous Analog Channel Estimation Aided Beamforming for Massive MIMO Systems
Vishnu V. Ratnam, Andreas F. Molisch
Analog beamforming greatly reduces the implementation cost of massive antenna transceivers by using only one up/down-conversion chain. However, it incurs a large pilot overhead whe…
