On the Coexistence of OTFS Modulation with OFDM-based Communication Systems Open
We investigate the coexistence of orthogonal time-frequency space (OTFS) modulation with current fourth- and fifth-generation (4G/5G) communication systems that primarily use orthogonal frequency-division multiplexing (OFDM) waveforms. We …

Access delay of the IEEE 802.11 MAC protocol under saturation Open
In this paper, we analyze the access delay of the IEEE 802.11 MAC protocol for the case when all stations are saturated. We obtain explicit expressions for the ¯rst two moments, and the generating function. We show via comparison with simu…

Urban 5G MmWave Networks: Line-of-Sight Probabilities and Optimal Site Locations Open
In this work, we implemented line-of-sight (LoS) ray tracing functionality to investigate problems in millimetre-wave propagation modelling and network planning in 3D city model environments. First, we validated an existing LoS propagation…

Delay-Doppler Domain Tomlinson-Harashima Precoding for OTFS-based Downlink MU-MIMO Transmissions: Linear Complexity Implementation and Scaling Law Analysis Open
Orthogonal time frequency space (OTFS) modulation is a recently proposed delay-Doppler (DD) domain communication scheme, which has shown promising performance in general wireless communications, especially over high-mobility channels. In t…

Maximizing the stable throughput of high-priority traffic for wireless cyber-physical systems Open
In wireless cyber-physical systems (CPS), more and more traffic with different priorities is required to be timely transmitted over wireless networks such as 802.11. In order to make full use of 802.11 networks to provide quality of servic…
