Spreading over OFDM for Integrated Sensing and Communications (ISAC) Ranging: Multi-user Interference Mitigation
Karim A. Said, Ibraheem Alturki, Husheng Li +2
In the context of communication-centric integrated sensing and communication (ISAC), the orthogonal frequency division multiplexing (OFDM) waveform was proven to be optimal in mini…
Reducing Inter-user Interference: Precoding over OFDM for Enhanced MTC
Karim A. Said, A. A. Louis Beex, Elizabeth Bentley +1
In the physical layer (PHY) of modern cellular systems, information is transmitted as a sequence of resource blocks (RBs) across various domains with each resource block limited to…
A Novel Interference Minimizing Waveform for Wireless Channels with Fractional Delay: Inter-block Interference Analysis
Karim A. Said, A. A., Beex +2
In the physical layer (PHY) of modern cellular systems, information is transmitted as a sequence of resource blocks (RBs) across various domains with each resource block limited to…
Maximally Concentrated Sequences after Half-sample Shifts
Karim A. Said, Lingjia Liu, A. A. +1
It is well known that index (discrete-time)-limited sampled sequences leak outside the support set when a band-limiting operation is applied. Similarly, a fractional shift causes a…
