Achievable Uplink Rates for Massive MIMO with Coarse Quantization
Christopher Mollén, Junil Choi, Erik G. Larsson +1
The high hardware complexity of a massive MIMO base station, which requires hundreds of radio chains, makes it challenging to build commercially. One way to reduce the hardware com…
Auxiliary Beam Pair Enabled AoD and AoA Estimation in Closed-Loop Large-Scale mmWave MIMO Systems
Dalin Zhu, Junil Choi, Robert W. Heath
Channel estimation is of critical importance in millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems. Due to the use of large antenna arrays, low-complexity mmWav…
Enhancing Secrecy with Multi-Antenna Transmission in Millimeter Wave Vehicular Communication Systems
Mohammed E. Eltayeb, Junil Choi, Tareq Y. Al-Naffouri +1
Millimeter wave (mmWave) vehicular communication systems will provide an abundance of bandwidth for the exchange of raw sensor data and support driver-assisted and safety-related f…
On the Security of Millimeter Wave Vehicular Communication Systems using Random Antenna Subsets
Mohammed E. Eltayeb, Junil Choi, Tareq Y. Al-Naffouri +1
Millimeter wave (mmWave) vehicular communica tion systems have the potential to improve traffic efficiency and safety. Lack of secure communication links, however, may lead to a fo…
Common Codebook Millimeter Wave Beam Design: Designing Beams for Both Sounding and Communication with Uniform Planar Arrays
Jiho Song, Junil Choi, David J. Love
Fifth generation (5G) wireless networks are expected to utilize wide bandwidths available at millimeter wave (mmWave) frequencies for enhancing system throughput. However, the unfa…
Uplink Performance of Wideband Massive MIMO with One-Bit ADCs
Christopher Mollén, Junil Choi, Erik G. Larsson +1
Analog-to-digital converters (ADCs) stand for a significant part of the total power consumption in a massive MIMO base station. One-bit ADCs are one way to reduce power consumption…
