Capacity Scaling of Massive MIMO in Strong Spatial Correlation Regimes
Junyoung Nam, Giuseppe Caire, Merouane Debbah +1
This paper investigates the capacity scaling of multicell massive MIMO systems in the presence of spatially correlated fading. In particular, we focus on the strong spatial correla…
On the High-SNR Capacity of the Gaussian Interference Channel and New Capacity Bounds
Junyoung Nam
The best outer bound on the capacity region of the two-user Gaussian Interference Channel (GIC) is known to be the intersection of regions of various bounds including genie-aided o…
Capacity Bounds for the -User Gaussian Interference Channel
Junyoung Nam
The capacity region of the -user Gaussian interference channel (GIC) is a long-standing open problem and even capacity outer bounds are little known in general. A significant pr…
On the Role of Transmit Correlation Diversity in Multiuser MIMO Systems
Junyoung Nam, Giuseppe Caire, Young-Jo Ko +1
Correlation across transmit antennas, in multiple antenna systems (MIMO), has been studied in various scenarios and has been shown to be detrimental or provide benefits depending o…
A Codebook-Based Limited Feedback System for Large-Scale MIMO
Junyoung Nam
In this paper, we consider limited feedback systems for FDD large-scale (massive) MIMO. A new codebook-based framework for multiuser (MU) MIMO downlink systems is introduced and th…
Fundamental Limits in Correlated Fading MIMO Broadcast Channels: Benefits of Transmit Correlation Diversity
Junyoung Nam
We investigate asymptotic capacity limits of the Gaussian MIMO broadcast channel (BC) with spatially correlated fading to understand when and how much transmit correlation helps th…
