Pilot Assignment for Distributed Massive MIMO Based on Channel Estimation Error Minimization
Mohd Saif Ali Khan, Karthik RM, Samar Agnihotri
Pilot contamination remains a major bottleneck in realizing the full potential of distributed massive MIMO systems. We propose two dynamic and scalable pilot assignment schemes des…
Decentralized Decoding with Adaptive Local Combining for Cell-Free Massive MIMO
Mohd Saif Ali Khan, Karthik RM, Samar Agnihotri
In existing literature, a two-stage architecture comprising of large-scale fading decoding (LSFD) at the central processing unit (CPU) and local combining at the access points (APs…
Latent Space Characterization of Autoencoder Variants
Anika Shrivastava, Renu Rameshan, Samar Agnihotri
Understanding the latent spaces learned by deep learning models is crucial in exploring how they represent and generate complex data. Autoencoders (AEs) have played a key role in t…
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…
