Capacity Analysis and Sum Rate Maximization for the SCMA Cellular Network Coexisting with D2D Communications
Yukai Liu, Wen Chen
Sparse code multiple access (SCMA) is the most concerning scheme among non-orthogonal multiple access (NOMA) technologies for 5G wireless communication new interface. Another effic…
IRS-aided Wireless Powered MEC Systems: TDMA or NOMA for Computation Offloading?
Guangji Chen, Qingqing Wu, Wen Chen +2
An intelligent reflecting surface (IRS)-aided wireless powered mobile edge computing (WP-MEC) system is conceived, where each device's computational task can be divided into two pa…
Beamforming Design and Power Allocation for Transmissive RMS-based Transmitter Architectures
Zhendong Li, Wen Chen, Huanqing Cao
This letter investigates a downlink multiple input single output (MISO) system based on transmissive reconfigurable metasurface (RMS) transmitter. Specifically, a transmitter desig…
