Sequential Processing Strategies in Fronthaul Constrained Cell-Free Massive MIMO Networks
Vida Ranjbar, Robbert Beerten, Marc Moonen +1
In a cell-free massive MIMO (CFmMIMO) network with a daisy-chain fronthaul, the amount of information that each access point (AP) needs to communicate with the next AP in the chain…
Exploring O-RAN Compression Techniques in Decentralized Distributed MIMO Systems: Reducing Fronthaul Load
Mostafa Rahmani, Junbo Zhao, Vida Ranjbar +4
This paper explores the application of uplink fronthaul compression techniques within Open RAN (O-RAN) to mitigate fronthaul load in decentralized distributed MIMO (DD-MIMO) system…
Cell-Free Massive MIMO under a Non-Linear Power Amplifier Consumption Model
Robbert Beerten, Vida Ranjbar, Hazem Sallouha +1
Existing works on Cell-Free Massive MIMO primarily focus on optimising system throughput and energy efficiency under high-traffic scenarios with only a limited focus on variable us…
Cell-free Massive MIMO with Sequential Fronthaul Architecture and Limited Memory Access Points
Vida Ranjbar, Robbert Beerten, Marc Moonen +1
Cell-free massive multiple-input multiple-output (CFmMIMO) is a paradigm that can improve users' spectral efficiency (SE) far beyond traditional cellular networks. Increased spatia…
Joint Sequential Fronthaul Quantization and Hardware Complexity Reduction in Uplink Cell-Free Massive MIMO Networks
Vida Ranjbar, Robbert Beerten, Marc Moonen +1
Fronthaul quantization causes a significant distortion in cell-free massive MIMO networks. Due to the limited capacity of fronthaul links, information exchange among access points…
Location-Based Load Balancing for Energy-Efficient Cell-Free Networks
Robbert Beerten, Vida Ranjbar, Andrea P. Guevara +2
Cell-Free Massive MIMO (CF mMIMO) has emerged as a potential enabler for future networks. It has been shown that these networks are much more energy-efficient than classical cellul…
