Thresholds optimization for one-bit feedback multi-user scheduling
(Institute of Electrical and Electronics Engineers Inc., 2018)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
DFT-based multi-directions directional modulation
(Institute of Electrical and Electronics Engineers, 2019)
In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ...
Secure spatial multiple access using directional modulation
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
Reducing precoder/channel mismatch and enhancing secrecy in practical MIMO systems using artificial signals
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)
Practical multiple-input-multiple-output (MIMO) systems depend on a predefined set of precoders to provide spatial multiplexing gain. This limitation on the flexibility of the precoders affects the overall performance. ...
