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…
A Primer on 3GPP Narrowband Internet of Things (NB-IoT)
Y. -P. Eric Wang, Xingqin Lin, Ansuman Adhikary +5
Narrowband Internet of Things (NB-IoT) is a new cellular technology introduced in 3GPP Release 13 for providing wide-area coverage for the Internet of Things (IoT). This article pr…
Random Access Preamble Design and Detection for 3GPP Narrowband IoT Systems
Xingqin Lin, Ansuman Adhikary, Y. -P. Eric Wang
Narrowband internet of things (NB-IoT) is an emerging cellular technology that will provide improved coverage for massive number of low-throughput low-cost devices with low device…
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…
