| Abstract: | A kind of carrier frequency estimation for inter-purle multi-carrier modulated signal is mentioned in this paper. By analysis the characteristics of signal's spectrum and instantaneous frequency spectrum, a method of multi-carrier frequency estimation is given. Through this method, FSK signal and mixed coding signal's carrier frequency and the correspondence between carrier frequency and time can be estimated. The error factors estimation algorithm is analyzed and simulation results show the effectiveness of the algorithm. |
