Overview of our recent results in signal analysis using recurrence plots

This paper highlights the main results of our research in the field of recurrence plot analysis in the last five years. It briefly discusses results in the study of the method itself, as well as in some applications of it, i.e. characterization of speech signals, detection and localization of partial discharges in electric cables, representation of transient signals, estimation of signal parameters, reduction of additive noise, and representation of digitally modulated signals (ASK, FSK, PSK, and OFDM).
