Permutation Matrix Modulation
Rahmat Faddli Siregar, Nandana Rajatheva, Matti Latva-Aho
We propose a novel scheme that allows MIMO system to modulate a set of permutation matrices to send more information bits, extending our initial work on the topic. This system is c…
Weighted Secrecy Coverage Analysis and the Impact of Friendly Jamming over UAV-Enabled Networks
X. A. Flores Cabezas, D. P. Moya Osorio, M. Latva-aho
In 5G and beyond networks, Unmanned Aerial Vehicles (UAV) are an attractive solution to enhance the secrecy of a wireless systems by exploiting their predominant LOS links and spac…
A Max-Min Task Offloading Algorithm for Mobile Edge Computing Using Non-Orthogonal Multiple Access
Vaibhav Kumar, Muhammad Fainan Hanif, Markku Juntti +1
To mitigate computational power gap between the network core and edges, mobile edge computing (MEC) is poised to play a fundamental role in future generations of wireless networks.…
Deep Neural Network-Based Blind Multiple User Detection for Grant-free Multi-User Shared Access
Thushan Sivalingam, Samad Ali, Nurul Huda Mahmood +2
Multi-user shared access (MUSA) is introduced as advanced code domain non-orthogonal complex spreading sequences to support a massive number of machine-type communications (MTC) de…
Deep Learning-Based Active User Detection for Grant-free SCMA Systems
Thushan Sivalingam, Samad Ali, Nurul Huda Mahmood +2
Grant-free random access and uplink non-orthogonal multiple access (NOMA) have been introduced to reduce transmission latency and signaling overhead in massive machine-type communi…
Massive MIMO with Radio Stripes for Indoor Wireless Energy Transfer
Onel L. A. López, Dileep Kumar, Richard Demo Souza +3
Radio frequency wireless energy transfer (WET) is a promising solution for powering autonomous Internet of Things (IoT) deployments. In this work, we leverage energy beamforming fo…
