The paper presents a method of selecting an optical channel for transporting the double-sideband radio-frequency-over-fiber (DSB-RFoF) radio signal over the optical fronthaul path, avoiding the dispersion-induced power penalty (DIPP) phenomenon. The

This paper presents a solution for enabling the coexistence of digitized radio-over-fiber (D-RoF) and analog radio-over-fiber (A-RoF) interfaces operating in the optical fronthaul of 5G mobile systems. In the first section, we formulate the need to i

An analysis of forced oscillations of cracked beam using statistical methods for periodically correlated random processes is presented. The oscillation realizations are obtained on the basis of numerical solutions of differential equations of the sec

Coherent symmetric averaging using a test period is employed for the estimation of the mean and the covariance function of periodically correlated random process (PCRP), when the period of non-stationarity is unknown. The period estimates are found a

We analyze the deterministic and stochastic components of the realizations of longitudinal vibrations of a rod weakened by a crack determined with the help of numerical solutions of a nonlinear differential equation with stochastic driving force. It
