Opportunistic Downlink Interference Alignment
Hyun Jong Yang, Won-Yong Shin, Bang Chul Jung +2
In this paper, we propose an opportunistic downlink interference alignment (ODIA) for interference-limited cellular downlink, which intelligently combines user scheduling and downl…
Linear Degrees of Freedom of the X-Channel with Delayed CSIT
Sina Lashgari, A. Salman Avestimehr, Changho Suh
We establish the degrees of freedom of the two-user X-channel with delayed channel knowledge at transmitters (i.e., delayed CSIT), assuming linear coding strategies at the transmit…
Degrees of Freedom of the Rank-deficient Interference Channel with Feedback
Sung Ho Chae, Changho Suh, Sae-Young Chung
We investigate the total degrees of freedom (DoF) of the K-user rank-deficient interference channel with feedback. For the two-user case, we characterize the total DoF by developin…
A New Achievable Scheme for Interference Relay Channels
Byungjun Kang, Si-Hyeon Lee, Sae-Young Chung +1
We establish an achievable rate region for discrete memoryless interference relay channels that consist of two source-destination pairs and one or more relays. We develop an achiev…
