What Role Can NOMA Play in Massive MIMO?
Kamil Senel, Hei Victor Cheng, Emil Björnson +1
This paper seeks to answer a simple but fundamental question: What role can NOMA play in massive MIMO? It is well-established that power-domain non-orthogonal multiple access (NOMA…
Humans and Machines can be Jointly Spatially Multiplexed by Massive MIMO
Kamil Senel, Emil Björnson, Erik G. Larsson
Future cellular networks are expected to support new communication paradigms such as machine-type communication (MTC) services along with conventional human-type communication (HTC…
Grant-Free Massive MTC-Enabled Massive MIMO: A Compressive Sensing Approach
Kamil Senel, Erik G. Larsson
A key challenge of massive MTC (mMTC), is the joint detection of device activity and decoding of data. The sparse characteristics of mMTC makes compressed sensing (CS) approaches a…
Optimal Base Station Design with Limited Fronthaul: Massive Bandwidth or Massive MIMO?
Kamil Senel, Emil Björnson, Erik G. Larsson
To reach a cost-efficient 5G architecture, the use of remote radio heads connected through a fronthaul to baseband controllers is a promising solution. However, the fronthaul links…
Device Activity and Embedded Information Bit Detection Using AMP in Massive MIMO
Kamil Senel, Erik G. Larsson
Future cellular networks will support a massive number of devices as a result of emerging technologies such as Internet-of-Things and sensor networks. Enhanced by machine type comm…
