Multiuser Diversity for Secrecy Communications Using Opportunistic Jammer Selection -- Secure DoF and Jammer Scaling Law
Jung Hoon Lee, Wan Choi
In this paper, we propose opportunistic jammer selection in a wireless security system for increasing the secure degrees of freedom (DoF) between a transmitter and a legitimate rec…
Optimal Feedback Rate Sharing Strategy in Zero-Forcing MIMO Broadcast Channels
Jung Hoon Lee, Wan Choi
In this paper, we consider a multiple-input multiple-output broadcast channel with limited feedback where all users share the feedback rates. Firstly, we find the optimal feedback…
Multiuser Diversity in Interfering Broadcast Channels: Achievable Degrees of Freedom and User Scaling Law
Jung Hoon Lee, Wan Choi, Bhaskar D. Rao
This paper investigates how multiuser dimensions can effectively be exploited for target degrees of freedom (DoF) in interfering broadcast channels (IBC) consisting of K-transmitte…
On the Achievable DoF and User Scaling Law of Opportunistic Interference Alignment in 3-Transmitter MIMO Interference Channels
Jung Hoon Lee, Wan Choi
In this paper, we propose opportunistic interference alignment (OIA) schemes for three-transmitter multiple-input multiple-output (MIMO) interference channels (ICs). In the propose…
