Subcarrier-wise Backscatter Communications over Ambient OFDM for Low Power IoT
Mahyar Nemati, Morteza Soltani, Jie Ding +1
Ambient backscatter communication (AmBC) over orthogonal-frequency-division-multiplexing (OFDM) signals has recently been proposed as an appealing technique for low power Internet-…
RIS-Assisted Coverage Enhancement in Millimeter-Wave Cellular Networks
Mahyar Nemati, Jihong Park, Jinho Choi
The use of millimeter-wave (mmWave) bandwidth is one key enabler to achieve the high data rates in the fifth-generation (5G) cellular systems. However, mmWave signals suffer from s…
Short-Range Ambient Backscatter Communication Using Reconfigurable Intelligent Surfaces
Mahyar Nemati, Jie Ding, Jinho Choi
Ambient backscatter communication (AmBC) has been introduced to address communication and power efficiency issues for short-range and low-power Internet-of-Things (IoT) application…
Machine Learning Enabled Preamble Collision Resolution in Distributed Massive MIMO
Jie Ding, Daiming Qu, Pei Liu +1
Preamble collision is a bottleneck that impairs the performance of random access (RA) user equipment (UE) in grant-free RA (GFRA). In this paper, by leveraging distributed massive…
IoT Connectivity Technologies and Applications: A Survey
Jie Ding, Mahyar Nemati, Chathurika Ranaweera +1
The Internet of Things (IoT) is rapidly becoming an integral part of our life and also multiple industries. We expect to see the number of IoT connected devices explosively grows a…
Opportunistic NOMA for Uplink Short-Message Delivery with a Delay Constraint
Jinho Choi
In this paper, we study the application of opportunistic non-orthogonal multiple access (NOMA) mode to short-message transmissions with user's power control under a finite power bu…
