MIMO Beampattern and Waveform Design with Low Resolution DACs
Amine Mezghani, Robert W. Heath
Digital beamforming and waveform generation techniques in MIMO radar offer enormous advantages in terms of flexibility and performance compared to conventional radar systems based…
Double-Sequence Frequency Synchronization for Wideband Millimeter-Wave Systems with Few-Bit ADCs
Dalin Zhu, Ralf Bendlin, Salam Akoum +2
In this paper, we propose and evaluate two novel double-sequence low-resolution frequency synchronization methods in millimeter-wave (mmWave) systems. In our system model, the base…
Linear Receivers in Non-stationary Massive MIMO Channels with Visibility Regions
Anum Ali, Elisabeth de Carvalho, Robert W. Heath
In a massive MIMO system with large arrays, the channel becomes spatially non-stationary. We study the impact of spatial non-stationarity characterized by visibility regions (VRs)…
Extremely Large Aperture Massive MIMO: Low Complexity Receiver Architectures
Abolfazl Amiri, Marko Angjelichinoski, Elisabeth de Carvalho +1
This paper focuses on new communication paradigms arising in massive multiple-input-multiple-output systems where the antenna array at the base station is of extremely large dimens…
Directional Frame Timing Synchronization in Wideband Millimeter-Wave Systems with Low-Resolution ADCs
Dalin Zhu, Ralf Bendlin, Salam Akoum +2
In this paper, we propose and evaluate a novel beamforming strategy for directional frame timing synchronization in wideband millimeter-wave (mmWave) systems operating with low-res…
Online Learning for Position-Aided Millimeter Wave Beam Training
Vutha Va, Takayuki Shimizu, Gaurav Bansal +1
Accurate beam alignment is essential for beam-based millimeter wave communications. Conventional beam sweeping solutions often have large overhead, which is unacceptable for mobile…
