Abstract A new algorithm based on Split-Symbol Moments Estimator (SSME) is provided in this paper to estimate blindly the chip rate of Direct Sequence Spread Spectrum (DS/SS) signal. The effectiveness of this algorithm is verified by analyzing the relationship between the symbol rate and chip rate, and the relationship between chip rate and Signal-to-Noise Ratio (SNR) in Additive White Gaussian Noise (AWGN). Computer simulation shows that this algorithm can estimate the chip rate successfully in low SNR and can enhance the accuracy of the chip rate estimation by increasing the length of the processed sampling data.
