In this paper, microwave photonic signal generation based on the period-one dynamic of optically injected discrete mode (DM) semiconductor lasers has been experimentally demonstrated and numerically simulated. The results show that frequency generated increases linearly with detuning or optical injection ratio. addition, a single feedback loop is sufficient to reduce linewidth without significa...

-Two new square root Kalman filtering algorithms are presented. Both algorithms are based on the spectral V A of the covariance matrix where V is the matrix whose columns are the eigenvectors of the covariance and A is the diagonal matrix of its eigenvalues. The algorithms use the covariance mode in the time propagation stage and the information mode in the measurement update stage. This switch...

In this paper, we propose a discrete-time nonlinear sliding mode observer for state and unknown input estimations of a class of single-input/single-output nonlinear uncertain systems. The uncertainties are characterized by a state-dependent vector and a scalar disturbance/unknown input. The discrete-time model is derived through Taylor series expansion together with nonlinear state transformati...
