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…
MmWave MU-MIMO for Aerial Networks
Travis Cuvelier, Robert W. Heath
Millimeter wave offers high bandwidth for air-to-air (A2A) communication. In this paper, we evaluate the rate performance of a multiuser MIMO (MU-MIMO) configuration where several…
High-Resolution Angle Tracking for Mobile Wideband Millimeter-Wave Systems with Antenna Array Calibration
Dalin Zhu, Junil Choi, Qian Cheng +2
Millimeter-wave (mmWave) systems use directional beams to support high-rate data communications. Small misalignment between the transmit and receive beams (e.g., due to the mobilit…
Algorithms for the Construction of Incoherent Frames Under Various Design Constraints
Cristian Rusu, Nuria Gonzalez-Prelcic, Robert W. Heath
Unit norm finite frames are generalizations of orthonormal bases with many applications in signal processing. An important property of a frame is its coherence, a measure of how cl…
