Non-orthogonal Multiple Access Assisted Multi-Region Geocast
Yi Zhang, Hui-Ming Wang, Zhiguo Ding +1
This work proposes a novel location-based multi-group multicast framework which is termed as non-orthogonal multiple access (NOMA) assisted multi-region geocast. This novel spectru…
Physical Layer Security in MIMO Backscatter Wireless Systems
Qian Yang, Hui-Ming Wang, Yi Zhang +1
Backscatter wireless communication is an emerging technique widely used in low-cost and low-power wireless systems, especially in passive radio frequency identification (RFID) syst…
Energy-Efficient Transmission Design in Non-Orthogonal Multiple Access
Yi Zhang, Hui-Ming Wang, Tong-Xing Zheng +1
Non-orthogonal multiple access (NOMA) is considered as a promising technology for improving the spectral efficiency (SE) in 5G. In this correspondence, we study the benefit of NOMA…
Secrecy Sum Rate Maximization in Non-Orthogonal Multiple Access
Yi Zhang, Hui-Ming Wang, Qian Yang +1
Non-orthogonal multiple access (NOMA) has been recognized as a promising technique for providing high data rates in 5G systems. This letter is to study physical layer security in a…
