Abstract
For non-cooperative communication, the symbol-rate estimation of digital communication signal is an important problem to be solved. In this letter, A new algorithm for the symbol-rate estimation of single-tone digitally modulated signal (i.e. MPSK/QAM) is proposed. Firstly a section from the received signal is cut as the template, and then the signal is matched sectionwise by making use of the signal selfsimilarity. So a signal containing the information of symbol jumping is got, and the symbol-rate can be estimated by DFT (Discrete Fourier Transformation). The validity of the new method has been verified by experiments.
