A new chip architecture from IBM can integrate nearly 100 billion transistors on a chip the size of a human fingernail—nearly twice the transistor density of the company’s previous generation of chip ...

Abstract: Prior works on physical-layer eavesdropping protection only addressed off-axis Eve. This paper presents the first TX to defend against both main-beam and off-axis Eves. Incorporating three ...

Abstract: A method was proposed for generating sum and difference beam patterns simultaneously in a sparse antenna array by utilizing a common excitation vector. This approach was motivated by the ...
