Energy Efficient Pairing and Power Optimization for NOMA UAV Network under QoS Constraints
Irfan Azam, Muhammad Basit Shahab, Soo Young Shin
Due to an increasing number of unmanned aerial vehicles (UAVs) with generally limited battery power, energy efficient data transmission schemes with massive connectivity capabiliti…
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…
Role Switching and Power Allocation Technique for Mobile Users in NOMA
Irfan Azam, Muhammad Basit Shahab, Soo Young Shin
In this letter, role switching and power allocation schemes are proposed to tackle user mobility in non-orthogonal multiple access (NOMA) systems. When cell center user (CCU) and c…
Grant-free Non-orthogonal Multiple Access for IoT: A Survey
Muhammad Basit Shahab, Rana Abbas, Mahyar Shirvanimoghaddam +1
Massive machine-type communications (mMTC) is one of the main three focus areas in the 5th generation (5G) of mobile standards to enable connectivity of a massive number of interne…
