Uplink Massive MIMO for Channels with Spatial Correlation
Ansuman Adhikary, Alexei Ashikhmin
A massive MIMO system entails a large number of base station antennas M serving a much smaller number of users. This leads to large gains in spectral and energy efficiency compared…
Uplink Interference Reduction in Large Scale Antenna Systems
Ansuman Adhikary, Alexei Ashikhmin, Thomas L. Marzetta
A massive MIMO system entails a large number (tens or hundreds) of base station antennas serving a much smaller number of terminals. These systems demonstrate large gains in spectr…
Massive-MIMO Meets HetNet: Interference Coordination Through Spatial Blanking
Ansuman Adhikary, Harpreet S. Dhillon, Giuseppe Caire
In this paper, we study the downlink performance of a heterogeneous cellular network (HetNet) where both macro and small cells share the same spectrum and hence interfere with each…
Joint Spatial Division and Multiplexing for mm-Wave Channels
Ansuman Adhikary, Ebrahim Al Safadi, Mathew Samimi +4
Massive MIMO systems are well-suited for mm-Wave communications, as large arrays can be built with reasonable form factors, and the high array gains enable reasonable coverage even…
Joint Spatial Division and Multiplexing: Opportunistic Beamforming and User Grouping
Ansuman Adhikary, Giuseppe Caire
Joint Spatial Division and Multiplexing (JSDM) is a recently proposed scheme to enable massive MIMO like gains and simplified system operations for Frequency Division Duplexing (FD…
Joint Spatial Division and Multiplexing
Ansuman Adhikary, Junyoung Nam, Jae-Young Ahn +1
We propose Joint Spatial Division and Multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to…
