Investigating Extreme Scattering Events by Volumetric Ray-tracing
Kelvin Au, Jason D. Fiege, Adam Rogers
Extreme scattering events (ESEs) are observed as dramatic () drops in flux density that occur over an extended period of weeks to months. Discrete plasma lensing structures…
Massive Machine-type Communications in 5G: Physical and MAC-layer solutions
Carsten Bockelmann, Nuno Pratas, Hosein Nikopour +5
Machine-type communications (MTC) are expected to play an essential role within future 5G systems. In the FP7 project METIS, MTC has been further classified into "massive Machine-T…
Uplink Contention Based SCMA for 5G Radio Access
Kelvin Au, Liqing Zhang, Hosein Nikopour +5
Fifth generation (5G) wireless networks are expected to support very diverse applications and terminals. Massive connectivity with a large number of devices is an important require…
SCMA for Downlink Multiple Access of 5G Wireless Networks
Hosein Nikopour, Eric Yi, Alireza Bayesteh +4
Sparse code multiple access (SCMA) is a new frequency domain non-orthogonal multiple-access technique which can improve spectral efficiency of wireless radio access. With SCMA, dif…
