Tensor Learning-based Precoder Codebooks for FD-MIMO Systems
Keerthana Bhogi, Chiranjib Saha, Harpreet S. Dhillon
This paper develops an efficient procedure for designing low-complexity codebooks for precoding in a full-dimension (FD) multiple-input multiple-output (MIMO) system with a uniform…
Meta Distribution of Downlink in a Poisson Cluster Process-based HetNet Model
Chiranjib Saha, Mehrnaz Afshang, Harpreet S. Dhillon
The performance analysis of heterogeneous cellular networks (HetNets), that relied mostly on the homogeneous Poisson point process (PPP) for the spatial distribution of the users a…
Learning on a Grassmann Manifold: CSI Quantization for Massive MIMO Systems
Keerthana Bhogi, Chiranjib Saha, Harpreet S. Dhillon
This paper focuses on the design of beamforming codebooks that maximize the average normalized beamforming gain for any underlying channel distribution. While the existing techniqu…
Load on the Typical Poisson Voronoi Cell with Clustered User Distribution
Chiranjib Saha, Harpreet S. Dhillon
In this letter, we characterize the distribution of the number of users associated with the typical base station (BS), termed the typical cell load, in a cellular network where the…
Machine Learning meets Stochastic Geometry: Determinantal Subset Selection for Wireless Networks
Chiranjib Saha, Harpreet S. Dhillon
In wireless networks, many problems can be formulated as subset selection problems where the goal is to select a subset from the ground set with the objective of maximizing some ob…
Millimeter Wave Integrated Access and Backhaul in 5G: Performance Analysis and Design Insights
Chiranjib Saha, Harpreet S. Dhillon
With the emergence of integrated access and backhaul (IAB) in the fifth generation (5G) of cellular networks, backhaul is no longer just a passive capacity constraint in cellular n…
