Physical-layer security is desirable for visible light communication (VLC) in order to hide information from unauthorized receivers, without reliance on upper-layer encryption. In this paper, we propose a physical-layer secure coding scheme based on polar codes to achieve secrecy capacity of indoor VLC under Wyner's wiretap model. Compared with the beamforming approach requiring multiple-input, single-output...
Cross regulation of single-inductor multiple-output (SIMO) boost dc/dc converter is usually considered as a key factor that degrades the voltage regulation of individual outputs. Analysis of the cross coupling of a single-switch single-input dual-output (SIDO) boost converter operating in continuous conduction mode (CCM) reveals that it is an automatic current feedback mechanism during converter operation,...
We investigate single-input mechanical control systems where the Lagrangian is the kinetic energy associated with a Riemannian metric. It is demonstrated that such a system is locally configuration controllable only if the dimension of the configuration manifold is one.
This paper considers the problem of estimating the domain of attraction(DA) for continuous-time single-input asymmetric saturated linear systems. The stability analysis is implemented based on the polyhedral Lyapunov function rather than on the classical quadratic Lyapunov function. According to the saturation property, the saturated linear systems are regarded as switched linear systems, and a new...
Coefficient assignment of the characteristic polynomial corresponding to a generalised linear system using state feedback laws is discussed. The equivalence of a method using Sylvester's equation to the methods of Ackermann and Bass-Gura is derived. The single-input case follows directly from the nonpolynomial case, but for multi-input it is demonstrated that a more stringent condition on the controllability...
