Coordinates-based Resource Allocation Through Supervised Machine Learning
Sahar Imtiaz, Sebastian Schiessl, Georgios P. Koudouridis +1
Appropriate allocation of system resources is essential for meeting the increased user-traffic demands in the next generation wireless technologies. Traditionally, the system relie…
NOMA in the Uplink: Delay Analysis with Imperfect CSI and Finite-Length Coding
Sebastian Schiessl, Mikael Skoglund, James Gross
We study whether using non-orthogonal multiple access (NOMA) in the uplink of a mobile network can improve the performance over orthogonal multiple access (OMA) when the system req…
Delay Performance of the Multiuser MISO Downlink under Imperfect CSI and Finite Length Coding
Sebastian Schiessl, James Gross, Mikael Skoglund +1
We use stochastic network calculus to investigate the delay performance of a multiuser MISO system with zero-forcing beamforming. First, we consider ideal assumptions with long cod…
Delay Performance of the Multiuser MISO Downlink
Sebastian Schiessl, James Gross, Giuseppe Caire
We analyze a MISO downlink channel where a multi-antenna transmitter communicates with a large number of single-antenna receivers. Using linear beamforming or nonlinear precoding t…
On the Reliability of LTE Random Access: Performance Bounds for Machine-to-Machine Burst Resolution Time
Mikhail Vilgelm, Sebastian Schiessl, Hussein Al-Zubaidy +2
Random Access Channel (RACH) has been identified as one of the major bottlenecks for accommodating massive number of machine-to-machine (M2M) users in LTE networks, especially for…
Delay Performance of Wireless Communications with Imperfect CSI and Finite Length Coding
Sebastian Schiessl, Hussein Al-Zubaidy, Mikael Skoglund +1
With the rise of critical machine-to-machine applications, next generation wireless communication systems must be designed with strict constraints on the latency and reliability. A…
On the Delay Performance of Interference Channels
Sebastian Schiessl, Farshad Naghibi, Hussein Al-Zubaidy +2
A deep understanding of the queuing performance of wireless networks is essential for the advancement of future wireless communications. The stochastic nature of wireless channels…
