[Communication-Mobile] ABlindEstimationAlgorithmforPNSequenceinDSSSSignal DL : 0: 这是一篇很好的有关信道估计的文章，可以用来快速的了解信道估计的基本内容-In this paper, a method for fast blind estimation of DS-SS signal is proposed which aims at the Direct-Sequence Spread- Spectrum (DS-SS) signals with parameters unknown. Considering the characteristic that Pseudo-Random noise (PN) sequence modulates the information symbol, we make use of the method based on the second-order cyclic-cumulant to estimate the period of PN sequence, and then the method of segmented cross-correlation to estimate the synchronous start bit between the information symbols and the PN codes. On base of this, a method of multiple subsection cross-correlation average is used to estimate the PN sequence. Computer simulations show that the method can work well on signals at low signal noise ratio (SNR).
