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…

Ergodic Interference Alignment with Delayed Feedback
Myung Gil Kang, Wan Choi
We propose new ergodic interference alignment techniques for -user interference channels with delayed feedback. Two delayed feedback scenarios are considered -- delayed channel…
