Inverse Multipath Fingerprinting for Millimeter Wave V2I Beam Alignment
Vutha Va, Junil Choi, Takayuki Shimizu +2
Efficient beam alignment is a crucial component in millimeter wave systems with analog beamforming, especially in fast-changing vehicular settings. This paper proposes a position-a…
Advanced Quantizer Designs for FDD-Based FD-MIMO Systems Using Uniform Planar Arrays
Jiho Song, Junil Choi, Taeyoung Kim +1
Massive multiple-input multiple-output (MIMO) systems, which utilize a large number of antennas at the base station, are expected to enhance network throughput by enabling improved…
IEEE 802.11ad-based Radar: An Approach to Joint Vehicular Communication-Radar System
Preeti Kumari, Junil Choi, Nuria Gonzalez-Prelcic +1
Millimeter-wave (mmWave) radar is widely used in vehicles for applications such as adaptive cruise control and collision avoidance. In this paper, we propose an IEEE 802.11ad-based…
Two-Dimensional AoD and AoA Acquisition for Wideband mmWave Systems with Cross-Polarized MIMO
Dalin Zhu, Junil Choi, Robert W. Heath
In this paper, a novel two-dimensional super-resolution angle-of-departure (AoD) and angle-of-arrival (AoA) estimation technique is proposed for wideband millimeter-wave multiple-i…
