Power-Time Channel Diversity (PTCD): A Novel Resource-Efficient Diversity Technique for 6G and Beyond
Ferdi Kara, Hakan Kaya, Halim Yanikomeroglu
Diversity techniques have been applied for decades to overcome the effects of fading, which is one of the most challenging problems in wireless communications due to the randomness…
Error Performance Analysis of Multi-user Detection in Uplink-NOMA with Adaptive -QAM
Hichem Semira, Ferdi Kara, Hakan Kaya +1
This work provides a generalized performance analysis for the multi-user uplink-NOMA system with adaptive square quadrature amplitude modulation (QAM) over Rayleigh fading channels…
A Lightweight Machine Learning Assisted Power Optimization for Minimum Error in NOMA-CRS over Nakagami- channels
Ferdi Kara, Hakan Kaya, Halim Yanikomeroglu
Non-orthogonal multiple access based cooperative relaying system (NOMA-CRS) has been proposed to alleviate the decay in spectral efficiency of the conventional CRS. However, existi…
Multi-user Joint Maximum-Likelihood Detection in Uplink NOMA-IoT Networks: Removing the Error Floor
Hichem Semira, Ferdi Kara, Hakan Kaya +1
The Internet of Things (IoT) framework requires a massive number of connection thus demanding spectral efficient solutions such as Non-Orthogonal Multiple Access (NOMA). However, t…
Error Performance of Uplink SIMO-NOMA with Joint Maximum-Likelihood and Adaptive M-PSK
Hichem Semira, Ferdi Kara
This paper studies the performance of the uplink Non-Orthogonal Multiple Access (NOMA) with Joint Maximum-Likelihood Detector (JML). We present a generalized upper bound of bit-err…
DeepMuD: Multi-user Detection for Uplink Grant-Free NOMA IoT Networks via Deep Learning
Ahmet Emir, Ferdi Kara, Hakan Kaya +1
In this letter, we propose a deep learning-aided multi-user detection (DeepMuD) in uplink non-orthogonal multiple access (NOMA) to empower the massive machine-type communication wh…
