Abstract :
Direct spread spectrum signal with high anti-interference property, It has the characteristics of pseudo noise. Research on direct spread spectrum signal parameter estimation has important practical significance. According to the transmission characteristics of direct spread spectrum signal, using the time domain correlation method to estimate pn code period and using the frequency domain smooth periodogram estimate chip rate, and using matrix decomposition method to restore the pseudo-code sequence, completed parameter estimation of direct spread spectrum signal.
