Sažetak:
An algorithm for optimizing the spread parameter of the reference signal (RS) in the recently proposed Cross Wigner-Ville distribution (XWVD) based method for the signal components instantaneous frequency (IF) estimation is presented. XWVD between the analyzed signal (AS) and the reference signal yields a scaled image closely resembling the IF laws of the signal components, provided a proper selection of the RS parameters has been made. The resulting image consists of the cross-terms between the AS and the RS, formed under strict geometrical rules which are subsequently exploited for signal components IF estimation. Since the method's performance strongly depends on the spread of the RS, an automatic optimization procedure based on differential evolution is proposed.
