Full-Duplex in Massive Multiple-Input Multiple-Output

open access: yesIEEE Open Journal of Vehicular Technology
In-band full-duplex (FD) operation can double the spectral efficiency of massive multiple-input multiple-output (mMIMO) systems by allowing simultaneous transmission and reception over the same time/frequency slot. However, the main challenge encountered

Downlink Multiple Input Multiple Output Mixed Sparse Code Multiple Access for 5G System

open access: yesIEEE Access, 2018
For downlink multiple-input multiple-output-sparse code multiple access (MIMO-SCMA) system, the convergence reliability of the detected codeword in each decision process is unsatisfactory at the message passing algorithm receiver. To address this problem,
