Beam-Coherence-Aware Two-Stage Digital Combining for mmWave MU-MIMO Systems
Yasaman Khorsandmanesh, Emil Bjornson, Joakim Jalden +1
This paper considers a wideband millimeter-wave MIMO system with fully digital transceivers at both the base station and the user equipment (UE), focusing on mobile scenarios. To r…

Quantized Precoding for Maximizing Sum Rate in MU-MIMO Systems with Constrained Fronthaul
Yasaman Khorsandmanesh, Alva Kosasih, Emil Björnson +1
This paper studies a downlink multi-user multiple-input multiple-output (MU-MIMO) system, where the precoding matrix is computed at a baseband unit (BBU) and then transmitted to th…

Splitting Precoding with Subspace Selection and Quantized Refinement for Massive MIMO
Yasaman Khorsandmanesh, Emil Bjornson, Joakim Jalden
Limited fronthaul capacity is a practical bottleneck in massive multiple-input multiple-output (MIMO) 5G architectures, where a base station (BS) consists of an advanced antenna sy…
