Mitigating Hand Blockage with Non-Directional Beamforming Codebooks
Vasanthan Raghavan, Ricardo A. Motos, M. Ali Tassoudji +3
Hand blockage leads to significant performance impairments at millimeter wave carrier frequencies. A number of prior works have characterized the loss in signal strength with the h…
Hand and Body Blockage Measurements with Form-Factor User Equipment at 28 GHz
Vasanthan Raghavan, Sonsay Noimanivone, Sung Kil Rho +8
Blockage by the human hand/body is an important impairment in realizing practical millimeter wave wireless systems. Prior works on blockage modeling are either based on theoretical…
Evolution of Physical-Layer Communications Research in the Post-5G Era
Vasanthan Raghavan, Junyi Li
The evolving Fifth Generation New Radio (5G-NR) cellular standardization efforts at the Third Generation Partnership Project (3GPP) brings into focus a number of questions on relev…
Antenna Placement and Performance Tradeoffs with Hand Blockage in Millimeter Wave Systems
Vasanthan Raghavan, Mei-Li, Chi +3
The ongoing commercial deployment of millimeter wave systems brings into focus a number of practical issues in form factor user equipment (UE) design. With wavelengths becoming sma…
Investigation of Performance in Integrated Access and Backhaul Networks
Muhammad Nazmul Islam, Navid Abedini, Georg Hampel +2
Wireless backhaul allows densification of mobile networks without incurring additional fiber deployment cost. This, in turn, leads to high spatial reuse, which is a significant too…
Channel Reconstruction-Based Hybrid Precoding for Millimeter Wave Multi-User MIMO Systems
Miguel R. Castellanos, Vasanthan Raghavan, Jung H. Ryu +4
The focus of this paper is on multi-user MIMO transmissions for millimeter wave systems with a hybrid precoding architecture at the base-station. To enable multi-user transmissions…
