HIGHLIGHTS
- who: SS symmetry and collaborators from the College of Electronic Engineering, National University of Defense Technology, Hefei, China have published the paper: Joint Resource Allocation for Frequency-Domain Artificial Noise Assisted Multiuser Wiretap OFDM Channels with Finite-Alphabet Inputs, in the Journal: Symmetry 2019, 11, 855 of /2019/
- what: With a suboptimal subcarrier allocation scheme the authors propose an efficient iterative algorithm to allocate the power between the information and the AN via the Lagrange duality method. Different from the Gaussian inputs , the authors develop a frequency-domain AN methodology with finite-alphabet symbols to . . .
