Energy Efficient Reconfigurable Intelligent Surface Enabled Mobile Edge Computing Networks with NOMA
Zhiyang Li, Ming Chen, Zhaohui Yang +4
Reconfigurable intelligent surface (RIS) has emerged as a promising technology for achieving high spectrum and energy efficiency in future wireless communication networks. In this…
Six constructions of asymptotically optimal codebooks via the character sums
Wei Lu, Xia Wu, Xiwang Cao +1
In this paper, using additive characters of finite field, we find a codebook which is equivalent to the measurement matrix in [20]. The advantage of our construction is that it can…
Two constructions of asymptotically optimal codebooks via the trace functions
Xia Wu, Wei Lu, Xiwang Cao +1
In this paper, we present two new constructions of complex codebooks with multiplicative characters, additive characters and trace functions over finite fields, and determine the m…
Effective Capacity and Power Allocation for Machine-Type Communication
Mohammad Shehab, Hirley Alves, Matti Latva-aho
Effective capacity (EC) determines the maximum communication rate subject to a particular delay constraint. In this work, we analyze the EC of ultra reliable Machine Type Communica…
Improving Wireless Physical Layer Security via D2D Communication
Hao Xu, Cunhua Pan, Wei Xu +3
This paper investigates the physical layer security issue of a device-to-device (D2D) underlaid cellular system with a multi-antenna base station (BS) and a multi-antenna eavesdrop…
Performance Analysis of User-centric Virtual Cell Dense Networks over mmWave Channels
Jianfeng Shi, Yinlu Wang, Hao Xu +2
This paper analyzes the ergodic capacity of a user-centric virtual cell (VC) dense network, where multiple access points (APs) form a VC for each user equipment (UE) and transmit d…
