On-off Switched Interference Alignment for Diversity Multiplexing Tradeoff Improvement in the 2-User X-Network with Two Antennas
Young-bin Kim, Myung Gil Kang, Wan Choi
To improve diversity gain in an interference channel and hence to maximize diversity multiplexing tradeoff (DMT), we propose on-off switched interference alignment (IA) where IA is…

The Degrees of Freedom of the Interference Channel with a Cognitive Relay under Delayed Feedback
Hyo Seung Kang, Myung Gil Kang, Wan Choi +1
This paper studies the interference channel with a cognitive relay (ICCR) under delayed feedback. Three types of delayed feedback are studied: delayed channel state information at…

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…
