Smaller Low-Depth Circuits for Kronecker Powers
Josh Alman, Yunfeng Guan, Ashwin Padaki
We give new, smaller constructions of constant-depth linear circuits for computing any matrix which is the Kronecker power of a fixed matrix. A standard argument (e.g., the mixed p…

Double-Sided Information Aided Temporal-Correlated Massive Access
Weifeng Zhu, Meixia Tao, Yunfeng Guan
This letter considers temporal-correlated massive access, where each device, once activated, is likely to transmit continuously over several consecutive frames. Motivated by that t…
