Adaptive Local Combining with Decentralized Decoding for Distributed Massive MIMO
Mohd Saif Ali Khan, Karthik RM, Samar Agnihotri
Efficient uplink processing in distributed massive multiple-input multiple-output (D-mMIMO) systems requires both effective local combining and scalable decoding to significantly m…
Energy-and Spectral-Efficiency Trade-off in Distributed Massive-MIMO Networks
Mohd Saif Ali Khan, Karthik RM, Samar Agnihotri
This paper investigates the energy efficiency (EE) and spectral efficiency (SE) trade-off in uplink distributed massive multiple-input multiple-output (D-mMIMO) systems. Unlike con…
Joint AP-UE Association and Power Factor Optimization for Distributed Massive MIMO
Mohd Saif Ali Khan, Samar Agnihotri, Karthik R. M
The uplink sum-throughput of distributed massive multiple-input-multiple-output (mMIMO) networks depends majorly on Access point (AP)-User Equipment (UE) association and power cont…
Distributed Resource Allocation for D2D Multicast in Underlay Cellular Networks
Mohd Saif Ali Khan, Ajay Bhardwaj, Samar Agnihotri
We address the problem of distributed resource allocation for multicast communication in device-to-device (D2D) enabled underlay cellular networks. The optimal resource allocation…
Distributed Pilot Assignment for Distributed Massive-MIMO Networks
Mohd Saif Ali Khan, Samar Agnihotri, Karthik R. M
Pilot contamination is a critical issue in distributed massive MIMO networks, where the reuse of pilot sequences due to limited availability of orthogonal pilots for channel estima…
