Interplay between VAoI, Packet Error Rate, and Delay for Energy-Efficient Remote Monitoring
Yasaman Khorsandmanesh, Zinat Behdad, Emil Bjornson +1
This letter studies energy optimization of short-packet transmission for event-triggered remote monitoring over finite-blocklength wireless links. A wireless sensor node generates…
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…
Joint Uplink-Downlink Fronthaul Bit Allocation in Fronthaul-Limited Massive MU-MIMO Systems
Yasaman Khorsandmanesh, Emil Bjornson, Joakim Jalden
This paper optimizes the fronthaul bit allocation in massive multi-user multiple-input multiple-output (MU-MIMO) systems operating with limited-capacity fronthaul links. We conside…
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…
