Clustering-based Joint Channel Estimation and Signal Detection for Grant-free NOMA
Ayoob Salari, Mahyar Shirvanimoghaddam, Muhammad Basit Shahab +2
We propose a joint channel estimation and signal detection technique for the uplink non-orthogonal multiple access using an unsupervised clustering approach. We apply the Gaussian…
Performance Analysis and Optimization of NOMA with HARQ for Short Packet Communications in Massive IoT
Fatemeh Ghanami, Ghosheh Abed Hodtani, Branka Vucetic +1
In this paper, we consider the massive non-orthogonal multiple access (NOMA) with hybrid automatic repeat request (HARQ) for short packet communications. To reduce the latency, eac…
A Revisit to Ordered Statistics Decoding: Distance Distribution and Decoding Rules
Chentao Yue, Mahyar Shirvanimoghaddam, Branka Vucetic +1
This paper revisits the ordered statistics decoding (OSD). It provides a comprehensive analysis of the OSD algorithm by characterizing the statistical properties, evolution and the…
Grant-Free Non-Orthogonal Multiple Access: A Key Enabler for 6G-IoT
Rana Abbas, Tao Huang, Basit Shahab +3
The proliferating number of devices with short payloads as well as low power budget has already driven researchers away from classical grant-based access schemes that are notorious…
