Optimal Photodetector Size for High-Speed Free-Space Optics Receivers

no code implementations16 Sep 2023 Muhammad Salman Bashir, Qasim Zeeshan Ahmed, Mohamed-Slim Alouini

The selection of an optimal photodetector area is closely linked to the attainment of higher data rates in optical wireless communication receivers.

Feature-Based Generalized Gaussian Distribution Method for NLoS Detection in Ultra-Wideband (UWB) Indoor Positioning System

no code implementations14 Apr 2023 Fuhu Che, Qasim Zeeshan Ahmed, Jaron Fontaine, Ben Van Herbruggen, Adnan Shahid, Eli de Poorter, Pavlos I. Lazaridis

However, it is difficult for existing ML approaches to maintain a high classification accuracy when the database contains a small number of NLoS signals and a large number of Line-of-Sight (LoS) signals.

Novel Fine-Tuned Attribute Weighted Naïve Bayes NLoS Classifier for UWB Positioning

no code implementations14 Apr 2023 Fuhu Che, Qasim Zeeshan Ahmed, Fahd Ahmed Khan, Faheem A. Khan

In this paper, we propose a novel Fine-Tuned attribute Weighted Na\"ive Bayes (FT-WNB) classifier to identify the Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) for UltraWide Bandwidth (UWB) signals in an Indoor Positioning System (IPS).

Anomaly Detection Based on Generalized Gaussian Distribution approach for Ultra-Wideband (UWB) Indoor Positioning System

no code implementations9 Aug 2021 Fuhu Che, Qasim Zeeshan Ahmed, Faheem A. Khan, Pavlos I. Lazaridis

The simulation results indicate that the proposed approach can provide a robust NLoS component identification which improves the NLoS signal classification accuracy which results in significant improvement in the UWB positioning system.

Reducing the Mutual Outage Probability of Cooperative Non-Orthogonal Multiple Access

no code implementations28 Oct 2020 Sana Riaz, Fahd Ahmed Khan, Sajid Saleem, Qasim Zeeshan Ahmed

Numerical simulation results show that the proposed scheme has a lower mutual outage probability (MOP) and offers better reliability as compared to the conventional power allocation scheme for CONOMA.

On Consideration of Content Preference and Sharing Willingness in D2D Assisted Offloading
