A novel method is presented for parameter estimation of multi‐component phase‐coded signals (PCSs). The algorithm is based on the short time Fourier transform (STFT), in which the high concentration of signals in the time‐frequency (TF) domain is used to separate each component, then the STFT zooming and phase jump mapping are proposed to estimate the carrier frequency (CF), symbol period and code sequence of each component. Feasibility of the presented method is demonstrated by experimental results.
