This paper introduces a new approach to providing secure physical-layer massive multiple-input multiple-output (MIMO) based communications that can improve the energy efficiency of the system.This is achieved by synthesizing orthogonal artificial noise (AN) that read more has to be constrained to lie in the null space of the legitimate users’
Two-component signal transduction systems enable bacteria to sense and respond to a wide range of environmental stimuli.Sensor histidine kinases transmit signals to their cognate response regulators via phosphorylation.The faithful transmission of information through two-component pathways and the avoidance of unwanted cross-talk require exquisite
