Abstract

Abstract

For the several kinds of pseudo-random code modulated pulse trains-the Pseudo-Random Binary Code (PRBC) pulse train, including the Pulse Position Modulation (PPM) pulse train, the Pseudo-Random Binary Code and Pulse Position Modulation (PRBC-PPM) pulse train, in order to solve the problem of single channel source separation and parameters estimation of multi-component signal, an estimation method of carrier frequency and pseudo-random code based on Singular Value Ratio (SVR) spectrum and cycle accumulation is proposed. The generalized period can be estimated through SVR spectrum firstly, after that the interference of the noise can be reduced by cycle accumulating, Fast Fourier Transformation (FFT) is used to analyze the squared signal, and the exact value of carrier frequency and the pulse position can be obtain by measuring the sum value of the real part of the signal which removed carrier frequency. At last, the amplitude and the initial phase can be determined by calculating the inner product. The simulation results prove that the proposed method is effective in different SNRs.
