Implement Blind Interference Alignment over Homogeneous 3-user 2x1 Broadcast Channel
Qing F. Zhou, Q. T. Zhang, Francis C. M. Lau
This paper first studies the homogeneous 3-user 2x1 broadcast channel (BC) with no CSIT. We show a sufficient condition for it to achieve the optimal 3/2 degrees of freedom (DoF) b…

Diophantine Approach to Blind Interference Alignment of Homogeneous K-user 2x1 MISO Broadcast Channels
Qing F. Zhou, Q. T. Zhang, Francis C. M. Lau
Although the sufficient condition for a blindly interference-aligned (BIA) 2-user 2x1 broadcast channel (BC) in homogeneous fading to achieve its maximal 4/3 DoF is well understood…

On the Blind Interference Alignment over Homogeneous Block Fading Channels
Qing F. Zhou, Q. T. Zhang
Staggered fading pattern between different users is crucial to interference alignment without CSIT, or so-called blind interference alignment (BIA). This special fading structure n…
