Degrees of Freedom of Over-the-Air Computation over a MIMO Gaussian Network with Two Transmitters and Two Receivers
Yong Dong, Hua Sun, Syed A. Jafar
The fundamental limits of over-the-air computation (AirComp) are explored in a two-transmitter, two-receiver MIMO Gaussian network, where both receivers demand the same aggregation…

Optimality of the Proper Gaussian Signal in Complex MIMO Wiretap Channels
Yong Dong, Yinfei Xu, Tong Zhang +1
The multiple-input multiple-output (MIMO) wiretap channel (WTC), which has a transmitter, a legitimate user and an eavesdropper, is a classic model for studying information theoret…
